Titleist FittingWorks Access to True Tour Fitting

Imagine traveling 180-200 days a year, working at close to 180 different events for almost 22 years. Meet Glenn Mahler, Titleist Advanced Fitting Specialist.
Once a teaching professional he has done fittings for Cobra before his current position fitting on the Titleist FittingWorks Van in
How many vans are there out there now? Is it just you and Pete Bezuk?
How does FittingWorks fit in with the Titleist Perfromance Institute experience? Is there a charge?
"TPI is the next step up but FittingWorks is still a rare opportunity for individuals to experience Tour level fitting. "We believe that the golf professionals should charge for their time for a fitting just like they charge for their time for a lesson. We do charge the facilities to bring our trailer on site, but it’s up to each facility to allocate these charges however appropriately they see fit and to dictate the pricing. We certainly don’t tell them how to price our services and we need to charge because of the level of expertise and all the technology we’re bringing plus our Mobile Workshop. It would also be a disservice, to the Golf Professional, if we came to their facility with everything we bring, and you saw how expansive that is, and did that for no charge. It would be very difficult for a golf professional to charge for their time if we didn’t even charge for ours."
"The availability, technology, and resources available on the van is unbelievable. All we’re trying to do is add a level of service. Just like you mentioned TPI, that’s something Titleist accounts can avail themselves to. This is another level of service we add above their own fitting carts and own local fitting experiences that we bring to their membership or customers. It’s not for everybody, but certainly our schedule is quite full and it seems to be the players we fit keep demanding it. So we’ve got to think we’re hitting up on the right chord. The need is there and the expertise is being appreciated."
The Titleist Approach to Fitting
How much do you depend on Technology and Cameras?
Glenn points out that mere accumulation of a launch monitor data, "does not a fitter make". One must interpret that data and use it to formulate the best plans in order to improve those numbers. In fact, he’s seen so many players and shots that he usually knows what the launch monitor will say before the data is even gathered. Basically, the monitor is there for the player and not the fitter since a fitter that has seen thousands of shots and will already know what the monitor will say.
"Regardless of a player’s handicap, I think fitters can blend technology and experience and can observe flight, record flight on launch monitors, cameras, and things like that, can use that information to then formulate a plan for the player.
Is it any easier to fit a Tour player vs a Weekend Warrior?
I don’t know that it’s any easier to fit a Tour player. I think any fitter can improve any player at any level" says Glenn. When someone goes for a fitting they should not expect to be taught anything about their swing. Glenn points out that,
"We’re not there to be their instructors. Most typically we’re at a facility that one day so we’re not really able to teach them and we’re not there as their instructor. What we can tell them is what the golf club is doing or what the golf ball is doing in flight or in the dynamics of when they swing. We can tell them what we believe to be these windows or ranges of what we like to see the golf club or golf ball do, for example in launch angle, spin rate, or dispersion, or path. The first thing that happens is an assessment of what is currently in the player’s bag."
"I like to see what a golfer does with their golf clubs. A lot of times you’ll see players are misfitted for length for example. I like to see what they do when they address the ball with their posture in their current set. Our philosophy is dynamic fitting – players swings and ball flights as opposed to static fitting where you take certain measurements and by these measurements you decide you need certain lie, or certain loft, or certain length. What dynamic fitting does is it takes into account what players do with their posture and their swing. I like to see what players do with their current set because if I do start making alterations I also want to see how much their swing is changing not by me asking them to make a change but by changing a specification in a golf club."
How do you go about fitting Players into Products?
"We have these four new iron models that have just been released this march – the ZM, ZB, AP1, and AP2. What I’ll do is I’ll go through that family and describe in detail the benefits and features of each model and what the engineers designed that model to do and also to tell them what we didn’t engineer that golf club to do. At that point we’ll allow the player to hit any and all of the models. We certainly do not direct players into a model. We let the player choose the model because looks and feel are certainly very important. But, we do want to make sure the player understands what the model was designed for because you’ll have your best opportunity as a player to succeed when you have this partnership or marriage with engineering. If you try to reverse-engineer you typically will fail because the engineers are better at design than you and I might be at reversing it. What I mean by that is let’s say a player hits all over the map on the face – they don’t hit on a consistent part of the club face. Yet they may like the ZM model. That ZM model we do not design to be forgiving, that’s not its purpose." The ZM is actually a traditional-type blade for those who want that sort of club. As opposed to like an AP2 or an AP1."
"They may like it, but I want to make sure they understand when they mishit that center of percussion, that ball speed is going to reduce pretty substantially. I just make sure they understand what the models are for. At the end of the day we’re in the people pleasing business. We want to make sure we please players. Part of pleasing players certainly is giving recommendations and specifications on golf equipment that allows them to be better.
Glenn, you mentioned the most common fault you have found is club length? We had heard from some of our members that Pros fitted by Titleist were going shorter in terms of shaft length?
"It’s amazing then when you start testing players and you start shortening the lengths for players how their ball-turf impacts improve. The strike locations move higher in the face where the ball speed increases, the launch angles go up, and the spin rates become appropriate for that particular loft golf club. They’re able to do it on a more repetitive basis and that is the key to a good, accomplished player. Whether it is a Touring Professional or an Amateur, when I see their ball speeds, for whatever club they’re hitting, it generally doesn’t vary more than 2 miles per hour from swing to swing. That makes for a repetitive carry distance and then players know how far they will carry a golf ball."
Is it a fair statement that the 6 iron is the "Benchmark" for irons for FittingWorks?
How does that compare from the swing instruction side where most people are taught to groove a 7 iron? Do people start to really struggle now once they get past a 6 iron? What is the set makeup you are starting to see more of now considering today’s common swing faults?
Since you are shortening the shaft and taking into account loft adjustments, how do you factor in the lie angle when fitting? You are known for your saying the the "lie board can lie."
"Well, I think other than ourselves, Callaway, and TaylorMade have similar standards on lies. As you know there’s no industry standard on lies.
"The demands come mostly from the consumer side, when we see most of the orders coming in at 62.5 it makes sense for us to make that our standard as opposed to 60.5. When a club has a shorter lie angle it is generally flatter. When you talk about a standard length club, whatever that length is, you’re usually going plus or minus on lie. When you go shorter you will typically stay standard or go flat. When you go long you will generally stay standard or go up. It’s a rare case that I will fit somebody long and flat and it’s a rare case I will fit somebody short and upright. It happens this way but it doesn’t happen very often. Just like I’m sure if you went through my personal specifications on irons, I probably fit a little bit more longer than standard than shorter but not much. Most of the irons I fit are probably at standard. So I go both ways. I’m not reluctant to go short just as I’m not reluctant to go long. I just let the evidence direct me where to go. I’m always directed by the evidence at impact and the ball flight."
What about indoor fittings? How much of a difference is an Outdoor vs an Indoor Fitting?
"Personally this is where I believe experience comes in the most. The technology is very helpful too, but, I believe I could be and excellent fitter indoor or outdoors. There are some things you’re going to have to be a little bit more aware of indoors because you can’t see the ball flight. I would spend much more time interviewing the Player in a couple of areas as that would be the most important part in terms of the indoor fitting. Currently there are three areas I accumulate information. I accumulate information from a player interview where I ask them, like I did you, their handicap, the strength of their game, the weakness of their game. "
"You have the player do a little self assessment for you. I like some history of where players tend to miss, what clubs they struggle with, what clubs they’re successful with, do they do better with fairways or hybrids or vice versa. So player interviews are important. Looking at their current set of clubs is equally important because that current set of golf clubs they own is like a crime scene."
"There are clues and evidence in those clubs. What I mean is I will look at strike locations on the face. I will take measurements of length and lie, start putting them in, and developing a synopsis of their game. Players tell me they tend to miss the ball left for example. And then I start seeing how those specifications work into that. Then finally ball flight, player swings ball flies. So ultimately all three areas, player interview, current set, and ball flight should tell you the same thing."
Let’s start drilling down on the products a bit. Specifically FittingWorks and irons.
How do you approach people concerning length when shortening their Irons?
"That’s a factor – everyone always talks about length, length, length but everyone’s irons are for scoring. A 5 iron usually plays into the longest par 4 you can get into. Also when you refer to length, another way we describe it is it’s not how far it goes, "it’s more important how far it goes once it hits the green because that’s going to determine where you putt from." Not many players can control their spin off of irons. Or if they have the right spin, maybe they don’t have the correct launch rate. So it’s being able to get these blends of both spin and launch for that speed and also for the type of greens you play. Here in Northern California where you play traditionally push up greens that are poa anna from back to front, the greens here in
Do you ever get any requests for Grinds on irons because of these different playing conditions? Also any feedback from players concerning the bounce on the AP 1 or AP 2?
![]()
"It doesn’t have too much bounce – it has a little bit more sole width. So it has a little bit more camber down there than the 695s and 704s. But I don’t think its bounce has increased over either of those models. I believe the bounce is the same; it just has a little more sole width. But that tungsten nickel down there low back toward the trailing edge has really helped increase the launch and definitely helped increase the forgiveness."
FittingWorks and Drivers
We read a lot of forum topics related to which irons are best for me but, we also get a fair amount of questions in regards to which is the hottest driver and which is the best shaft for it?
"I would say in the last couple of years out of our fitting trailer we do primarily irons and wedges. It’s not that we don’t do drivers, but most players come to us for irons and wedges. That’s not something we dictate, that’s something they choose. One reason I think this is because most golf clubs, most golf shops have a lot of different demo clubs to try out. And players take them out and check them out and take them out on the course. Each player knows how far they hit the ball on their course and they’ve tried different manufacturers, different lofts, and different shafts. Over time they’ve figured out this driver doesn’t go any further than mine."
"I’ll give you an example, we were down in
What has been your experience with D1 and D2 Titleist Drivers so far? What are some factors you are looking for in optimal player performance? Have you ever seen it where numbers seen completely out of tune?
"Again, it’s a range. I’m not going to give you one number because it’s so variable. For better players who have ball speed of anywhere between 145 and 160 mph, we’re going to see launch rates in a window from 10-14 degrees and spin rates might be anywhere from 2200 – 2700."
For a time there, everyone was going lower loft. Now it seems that people have started to go higher because of spin rates and launch angles. Have you noticed this?
How has increasing the CC’s over the years effected fitting?
How does working with the Cobra Brand help you with FittingWorks?
"They make several products that are designed for better ball flights. But most of their products are designed to get the ball up and more draw bias. So it’s certainly the bulk of majority of players in golf need that type of flight. Their products are engineered to enhance those flights and that’s why they create them and why they’re so successful."
FittingWorks and Wedges
How do you fit wedges at facilities? Do you visit many facilities where you can do bunker fittings?
"Maybe
How would you assess the availability of different wedge grinds today and what FittingWorks offers?
Are you seeing grinds on 52*, 54* and 56* Wedges too?
Typically not as much because those generally aren’t clubs you open up as much. You might do a little more in a 54 or 56, but 52 is mainly a club that’s played from neutral to if anything you’re taking it down a little bit, taking the loft off at times. What I mean by taking the loft off, you’re trying to hit lower shots in and so you probably don’t do near as much in 54s and 56s as you do in 58s."
Since this is a FittingWorks Tour Van, do you do any grinding of wedges?
FittingWorks and Putters
"With our fitting trailer, we do all 13, what I call "air assault" clubs. So everything that’s up in the air, we fit. We don’t fit any putters, but we do repairs or alterations, adjust the lie and the loft of the putter should a player need to. And we’ll do things like re-grip. So we’ll re-grip their putters with a wide stock of grips from what’s available from the factory. But we can re-grip a putter, things like that."
Finally Glenn, What’s in the Bag???
I’ve got an F4, 15.5, and F4 18.5 and both those just have a YS-6 stiff and they’re both a half inch short. Actually the 3-wood is an inch short and the five wood is a half inch short.
I play AP-2 3-PW with Dynalite Gold S300, -.25
I play a Vokey 52.08, and a Vokey 56.14. I just carry three wedges. I’m old school. I don’t play very much. I don’t practice very much. I didn’t grow up playing a 60, I never really learned to hit a 60 so I’m quite accustomed to hitting high shots with a 56. I could probably do it a lot better with a 60, but I don’t have the opportunity to practice.

Why Rickie Fowler is switching to a shorter driver at the PGA Championship
In a golf world where players are looking to eke out every yard possible, usually by lengthening their drivers to add clubhead speed, there’s one player at the PGA Championship who’s going in the opposite direction. In fact, for Rickie Fowler, his goal off the tee is not about gaining extra distance or yards north to south, but rather about shrinking the misses from east to west.
Ahead of the PGA Championship and the week prior at the Truist Championship. Fowler mentioned to Cobra Tour Rep Ben Schomin that the driver didn’t quite swing feel the same as everything in the bag. As a result, and with Schomin’s suggestion to try and sync everything up with the big stick, Fowler decided to test out a shorter length shaft.
“He’s been at 45 (inches), and he’d been at 45 for a few weeks, 44 1/8 (inches) is really is where he is been living really for the most part, for the last couple of years, and is where he is been comfortable,” Schomin told GolfWRX. “It just felt like it was a little long and loose on him.”
Interestingly, Fowler ranks 40th in Driving Accuracy this year on the PGA Tour. It’s his most accurate season with the driver since the start of the decade. But sometimes for players, feel is more important than statistics.
“It was really more of a trying to get the swing to feel the fluidness from club to club to club to try to get it to feel the same,” Schomin added. “And so we took it down to 43 and a quarter, and it was a touch of a ball speed loss, just based on that overall club head speed. But honestly, he squared it up probably a little better. The right miss wasn’t nearly as far. So really, overall down-range dispersion tightened up a fair amount, and he felt confident in swinging it.”
The change in length had Fowler’s caddie, Ricky Romano, beaming at how well he had driven during Tuesday’s practice round at Aronimink. So much so, he was asking Schomin not to suggest changes anymore.
Fowler’s shaft-shortening is one of a few driver adjustments he’s made this season, and to Schomin’s credit, it’s thanks to the fact that he and the rest of the Cobra team had Fowler fit very well into three of the four heads in the Cobra OPTM lineup.
“He had three distinct drivers and the biggest decision was trying to decide which worked best at that time,” Schomin told GolfWRX previously. “He’s played the majority of the season with OPTM X, but has also played a couple of tournaments with OPTM LS. His overall driving stats have been good.”
At the RBC Heritage earlier this spring, Fowler switched drivers, changing from his Cobra OPTM X and into the Tour, low-loft Max K model that Gary Woodland used to win just a few weeks prior.
Now for the PGA Championship, Fowler’s back in the X head, but still using the UST Mamiya LIN-Q PowerCore White 6TX shaft, just a little bit shorter.
“Will he stay there? I’m not sure,” Schomin added. “Could we end up say at like 43 and 7.5 (of an inch). If it’s giving him the same feel of consistency through the bag, then I think we might end up just a touch longer. But if he likes where he is at, he’s confident where he is at, that’s really all that matters.”
If there’s more testing, though, just don’t tell his caddie.

GolfWRX Launch Report: 2026 Titleist GTS drivers
What you need to know: As is customary for the Fairhaven-based company, Titleist officially announced today that its GTS drivers are headed to retail, following a successful tour release. The GTS2, GTS3, and GTS4 drivers will be available in golf shops June 11.
Since debuting at the Texas Children’s Houston Open, the new GTS lineup has quickly gained traction on the PGA Tour, with more than 50 players already making the switch to a GTS2, GTS3, or GTS4 driver. Among them are Justin Thomas and Jordan Spieth.

Justin Thomas’ Titleist GTS2 driver (Greg Moore, GolfWRX)
According to Titleist, the GTS series builds upon the performance foundation established by the GT Series, while introducing several major technological advancements, including a new Split Mass Frame construction, refined aerodynamics, and an updated Speed Sync face design.

2026 Titleist GTS drivers: What’s new, key technology
Split Mass Frame and thermoform body
At the center of the new GTS lineup is a redesigned internal structure: the Split Mass Frame. This technology works with a full-thermoform body made from Titleist’s Proprietary Matrix Polymer (PMP), a lightweight composite that enables engineers to reposition mass more efficiently throughout the head. Compared to the previous GT generation, GTS drivers feature nearly double the PMP material, increasing from 13 grams to 26 grams, while maintaining the sound and feel preferred by better players.
The weight savings from the thermoform construction allowed Titleist engineers to strategically separate mass placement inside the head. Specifically, more weight is pushed rearward to improve stability and forgiveness, while additional mass is positioned low and forward to optimize speed, launch, and spin.
In short, golfers are able to maintain ball speed and consistency across both centered and off-center strikes.

Faster aerodynamics
Titleist also refined the aerodynamic shaping of the GTS heads to help players generate more clubhead speed.
The tails of the new GTS2 and GTS3 heads have been raised compared to previous models, helping airflow stay attached to the crown and sole longer during the swing. According to Titleist, the improved airflow reduces drag and increases speed without affecting launch conditions or center of gravity placement.
Typically, aerodynamic gains can compromise forgiveness or launch characteristics, but the weight savings from the Split Mass Frame allowed engineers to preserve preferred CG locations.

New Speed Sync face
The new Speed Sync Face design is engineered to improve ball speed retention across a larger portion of the face. A reinforced perimeter structure helps maximize face deflection and COR on centered strikes, while the upper portion of the support ring is opened up to increase speed on high-face impacts, a common strike location for many golfers. The face also features a variable thickness design to preserve speed and performance across a wider impact area.
Expanded adjustability
Each GTS model includes a dual-weighting system to fine-tune launch, spin, and shot shape more precisely than previous generations. GTS2 uses interchangeable forward and aft weights, while GTS3 and GTS4 combine a rear weight with an adjustable forward track weight system.
Tour-inspired face graphics
The new lineup features redesigned high-contrast face graphics to improve alignment and framing at address, according to Titleist. Sharp visual lines are designed to make it easier to center the golf ball and to perceive loft more easily at setup.

Additional model details
GTS2

- The GTS2 is the most forgiving model, designed for golfers seeking maximum stability and consistent speed across the face.
- It produces high launch with mid spin and features a larger, confidence-inspiring profile behind the ball.
- Standard weighting includes an 11-gram forward weight and a 5-gram rear weight, with additional fitting configurations available.
GTS3

- The GTS3 is aimed at players who want more control over launch, spin, and shot shaping.
- Compared to GTS2, the GTS3 offers lower launch and spin while featuring a more compact profile and deeper face design preferred by many stronger players.
- The head features an adjustable forward-track weight system to further fine-tune center of gravity placement.
GTS4

- The lowest-spinning option in the lineup, GTS4 is built for golfers looking to reduce excessive spin and maximize total distance.
- Unlike previous “4” models from Titleist, the new GTS4 features a full 460cc profile that improves forgiveness and stability while retaining its low-spin DNA.
- Like GTS3, it includes a forward track weighting system for precise fitting adjustments.

What Titleist says
“When we talk about driver design, it’s never about the one feature or benefit — it’s about all of them,” said Stephanie Luttrell, Titleist’s Senior Director of Metalwood R&D. “Ball speed, forgiveness, spin stability, adjustability, exceptional sound and feel… these are all attributes that golfers care about. It’s our job to design a lineup that elevates performance across the board without sacrificing in key areas, and we feel we’ve done that with GTS.”
“We know that forward CGs drive speed with great launch and spin characteristics, but you need to be able to do that with an inertial stability that still preserves ball speed, launch and spin consistency on off-center hits,” Luttrell said. “We’ve never before been able to hit these CG positions and inertia properties at the same time, and we’re achieving that because of GTS’ construction.”
Club Junkie’s take
I feel like every time there is a new Titleist wood release, I figure they can’t outdo their previous driver. And every year, I am wrong and impressed with the performance. The GTS fits right into that narrative again, as I didn’t know where Titleist could go from GT, but they pushed the limits again, and my fitting proved the smart people there found ways to improve.
My past four Titleist drivers have been a 2 series as my swing typically requires a little height, spin, and forgiveness so I figured I would just get a new GTS2 and be on my way. During the fitting, I was impressed by the new GTS construction, its added PMP material, and the advanced adjustability on each model. My fitter, Joey, got to work putting together a GTS2 and we started there. The launch and spin were great, and the consistency on misses was very tight. My average ball speed with the GTS went up a little bit as the new Speed Sync face creates more speed away from the center.
Joey then built up a GTS3 in 11 degrees, but I figured this wouldn’t have the stability I needed for tight dispersion on my miss hits. That thought was quickly erased after a few shots, and I really liked the more center start line and reduced draw on the misses I was seeing. We tried a few different settings and shafts to dial in the details in order to get the best fit. Having a forward and rear weight in the head allowed Joey to set up the GTS3 with a heavier rear weight to keep the launch and spin up, while the Sure Fit hosel set flat created a more center start line for me. My misses were not nearly as far left, and I was really impressed with the consistency on the spin and launch when I didn’t hit it in the center.
Titleist again created a wood line in GTS that delivers improvements over previous drivers while keeping the traditional look and feel you expect. More adjustability, better off-center speed, and 3 drivers that are playable over a wider range of players should make these extremely successful in fittings.

It’s not a common result, but it might very well be what you need … generally that kind of result tends to appear with shorter than average people with rather short arms AND a out to in swingplane. If that is the case and you do not want to work on your swing and change it – that specc is probably correct for you
ot – dynamic fitting is the way to go if you have a student who has a settled swing and is not about to change that in the near future. less skilled golfers are very often better off with clubs that are closer to their static results since every golfer tends to adapt to his clubs … and if the clubs are the right speccs – the adaption makes your swing better 😉

Great article! I was fitted for the AP1 but will put off the purchase until Jan. My worry is I was fitted for 1/2 short & 2*up and in the article, Glenn says almost all the time he sees shorter length, go negative lie and longer shaft length, go more upright, which is just opposite of my setup… But I have used the lie board and impact tape and the readings seem correct.
Any input on this?
