The Wedge Guy: Swing Weight Part 2 – Non-standard lengths

Published

on

This is the part of the swingweight discussion where I expect to get lots of dialog, so here goes.

The modern trend in clubfitting seems to “fit” many golfers long and upright, which I don’t necessarily agree with, but can sound off on that later. Today, we’re going to talk about this subject, and I’m going to share my theory on what does and should happen to swingweight.

The idea of fitting a golfer with longer shafts is to accommodate his or her height and posture. Let’s say my friend who’s 6’3” really likes my irons, and wants a set “just like them”, but he wants them built to his own specs of 1” overlength. So, to accommodate his larger size and assumed strength, we build him a set of irons just like mine, except that the shafts 1 inch longer than mine are. Now, that one inch in the butt of the golf club shaft only adds about 2 grams to the overall weight of the club, and does nothing to the flex profile. So his new irons are EXACTLY like mine – same shaft flex, same heads, same everything.

BUT, when we put his new irons on the swingweight scale, he goes ballistic, because they read D7-9, rather than the D2 that I play. But they are not heavier than mine: they are just like mine, only altered to accommodate his size.

However, if he insists that they should be only D2, as a clubmaker, I have my work cut out for me. First, I have to grind weight off the clubheads . . . considerable weight, as much as 5-8% of the mass . . . with greatly alters the club, right? And removing that much mass then makes the shafts play much stiffer, increasing the frequency by a half a flex or more. So, in order to “match” the swingweight, I’ve created a tremendously lighter and stiffer club – nothing like the irons I have that he liked so much.

Or I guess I could counter-weight the club significantly, which also is dramatically changing the irons that we wanted to be “just like mine.”

What I have always proposed is that we think in the concept of “swingweight equivalent”. If the club is D2 at standard length, it’s going to be D4-5 at 1/2” over, maybe D8-9 at 1” over. When we are making shaft length adjustments that are shorter, that exact same club will be C9 or so at 1/2” shorter than standard.

I really think it’s just that simple. What about all of you?

Terry Koehler is a fourth generation Texan and a graduate of Texas A&M University. Over his 40-year career in the golf industry, he has created over 100 putter designs and dozens of wedges. In 2014, he put together the team that reintroduced the Ben Hogan brand to the golf equipment industry with his TK 15 wedges and Ft. Worth 15 iron designs. Since receiving a U.S. Patent for his “Koehler Sole” in the early 1990s, he has been challenging “conventional wisdom” in the wedge category. In addition to inspiring multiple companies to emulate this sole technology, the performance of his wedge designs have stimulated all other companies to reposition some mass toward the top of the blade in their wedges. Terry is retired from his role as Chairman and Director of Innovation for Edison Golf, and remains active in the industry as an independent designer and consultant.  But his most compelling work is in the wedge category. Since he first patented his “Koehler Sole” in the early 1990s, he has been challenging “conventional wisdom” reflected in ‘tour design’ wedges. The performance of his wedge designs have stimulated other companies to move slightly more mass toward the top of the blade in their wedges, but none approach the dramatic design of his Edison Forged wedges, which have been robotically proven to significantly raise the bar for wedge performance.

    If he likes your clubs, then why change the specs? Just because he is taller than you,which most people are, (lol) does not mean he needs longer clubs. It is about being able to square the clubface at the ball!!

    He hit your clubs and liked them! Why change? Maybe your length is the length he really needs. It may allow him to set up to the ball properly and square the clubface at impact. I am sure he is probably taller than you and because of his height was fitted with longer clubs.

    @mark brooks, suggest to you that many brilliant scientists and inventors design
    off the shelf golf shafts to be as cheap to make as possible.
    How much value is in 99% of all shafts in play(off the shelf) when their made for
    $5-$10 each.

    IMO you need to go to after market shafts in order to get any consistency of CPM.
    Xi iron shafts (cpm over 300 within recommended lengths) are as tip stiff as is possible for a graphite shaft within the given hosel diameter. Butt cut only is a good sign of a tip stiff shaft.

    Ben Hogan’s clubs were C7-C9 SW for a reason. He swung the grip end of the club
    He didnt throw the clubhead which is the tendency with high SW clubs.

    I agree with this premise, at least in theory, Terry! In addition, many (but certainly far from all) golfers who need or prefer longer-than-standard playing length clubs are also stronger than your average golfer. These guys can, and often do, play much better with clubs that have a slightly higher swingweight. I know that I prefer the swingweight on all of my clubs to be at least D3-D4, and on my wedges, I want the swingweights to be above D5 or D6. I work out extensively and am far stronger than the average guy my age (71) and probably stronger than most guys in their 30s. Thus, I prefer clubs with a heavier swingweight, and play better golf when using them.

    I am a mechanical engineer and studied objects in motion, like golf clubs, rather extensively. Isaac Newton proposed laws of motion along with mathematical methods in 1687, and these fundamentals have been verified in thousands of experiments and predictions. Newton’s laws and mathematics are not to be questioned: they describe motion of visible objects over a wide range of velocities.
    Swingweight is a balance property like two children on a see-saw – swingweight is a length times distance function: the lighter child is on the longer end of the see-saw.
    Now the conclusion: Newton’s mathematical equations of motion do NOT contain any length times distance terms. Therefore swingweight is irrelevant to golf club motion. Forget about swingweight and play what works for you!!
    Newton does provide a club matching parameter, but that is a topic for a whole different discussion.

    It’s not as simple as just excepting the 6 point swing weight increase at 1” over because the MOI is not the same and therefore the feel, performance, and effort required to swing the club are not the same as a standard length D2 swing weighted club.

    The problem is that the industry should not be using swing weight to begin with. It’s archaic and pointless. It’s much like building a club to a specific frequency. Swing weight and frequency are only accurate measurements when you are trying to replicate the EXACT SAME CLUB. You cannot build a club at a different length, weight, or with a different shaft and obtain a “match” by using swing weight and frequency.

    In regards to the shaft, the amount of deflection does change when you simply lengthen the club even though the ei profile is not altered. So, the dynamic bending of the shaft is changed and influenced by the added length even without a change to the profile.

      On target: replicate a GIVEN clob, but not match a set. Club MOI is a valid matching parameter; hence the matched feel of single length clubs.

    What about needing shorter lengths – 1/2 to 1 inch length? Have always heard if club already made get out the lead tape. Best to order special from factory and the manufacturer will use slightly heavier heads.
    Have wondered if it would be better mfg cut shaft off at both ends differently to achieve the required length with same feel.

    “long and upright”?
    If longer, wouldnt it be logical to flatten the lie angle?

    Dont golfers know by now that upright golf swings take a toll
    on the body? After Tiger swung at his best in 2000
    the gurus took his swing upright and we see the result
    in damaged knees and lower back.
    Drop into the Slot and Turn..
    like Tiger in 2000, Ben Hogan and the G.O.A.T, Jack Nicklaus.

      You think that swinging a shorter club (which typically means more static weight as well) while bent over more to accommodate that is easier on the body and less injury prone? I can’t think of anything worse for your back than trying to bend and turn and a high rate of speed.

      A bit anecdotal, but I rarely hear of baseball players having lower back issues yet for golfers back problems are quite common. Granted the swings are on different planes, but the posture and orientation of the spine are quite different between the two while swinging with great amounts of force. I’ll take the golf swing with the more upright posture and increased extension all day long personally over the tilted and increased side bend move that is being taught by so many.

        Jul 18, 2020 at 9:56 am

        IMO my hands want the butt of the club to be the same height from the ground for every club.

        If the shaft is shorter or longer the lie angle is changed so hands on every club is swung from the same height from the ground.

        Changing the swing (more upright) to adjust to a golf club
        is going to lead to injury, IMO.

        Babe Ruth, arguably the best baseball swing with plane of the swing mimicking the hips, much like Ben Hogans swing, so called flat swing.

        Its no wonder baseball doesnt seem to have the knee and back problems golfers experience with upright swings.

      Jul 22, 2024 at 2:05 am

      WTF? Tiger went to a flatter plane after 2000. Not upright…lol. Haney had him flatter at the top. Because of Hogan. U cray cray.

    An inch longer golf club will not have the same “flex” or CPM reading.
    The stiffest section of the vast majority of shafts is in the butt section, effectively there is an inch longer section remaining on the butt end of the shaft at an inch longer provided no tip trimming was done. If the swing weight was indeed adjusted to match the swing weight of the shorter club, the longer club should be stiffer by any measure of “flex”. Allowing the club to just “naturally “ move to a heavier swing weight will generally make that longer, now heavier swing weight club “play” and measure as the softer or more flexible of the two clubs.
    The longer shaft is simply easier to bend than the shorter one with equal weight on both ends. The more length added the more dramatic the change. Conversely, a 1/4 inch change will yield very little change in “feel” or performance.
    The golf shaft manufacturer’s employ many brilliant scientists and inventors, they design their shafts to perform the best within a reasonable set of parameters, including overall club length. When you stray too far outside designed for parameters, you’re essentially on your own. Hope this helps out !

Brandel Chamblee PGA Championship Q&A: Rose’s huge McLaren risk, distracted LIV pros and why Aronimink suits the bombers

Published

on

PGA Championship week is here, and Brandel Chamblee did not hold back in our latest discussion ahead of the season’s second major.

In our 2026 PGA Championship Q&A, golf’s leading analyst made the case that PIF pulling LIV’s funding has left its players competing in a state of confusion, called Justin Rose’s mid-season equipment switch a huge risk at 45, and explained why Aronimink will be a bombers’ delight this week.

Check out the full Q&A below.

Gianni: With the PIF confirming that they’re pulling funding from LIV at the end of the season, what impact do you expect that to have on the LIV players competing at the PGA Championship?

Brandel: I would imagine that they have all been thrown into a state of confusion, and will be distracted, not knowing where they are going to play next year and not knowing exactly their road back to either the DP World Tour or the PGA Tour. Or in Rahm’s case, being tied to a sinking ship for the next few years, likely playing for pennies on the dollar in events that no one cares about or watches.

I doubt this would put him in the best frame of mind to compete at his highest level. Keeping in mind, however, that majors are the only time that LIV disciples get to play in events that matter, so never disregard the motivation they have to prove to the world they are still relevant.

Gianni: Justin Rose switched to McLaren Golf equipment mid-season while playing some of the best golf of his career. What do you make of the change?

Brandel: I don’t really know what to make of Rose switching equipment. It seems a huge risk on his part, even though it is likely, in my opinion, that the clubs he’s playing are similar, if not the exact grinds, to what he was playing previously, with a McLaren stamp on them.

Having said that, at best, it is a distraction when he seemed to be as dialed in with his game as any 45-year-old could be and trending in the majors to perhaps do something that would definitely put him in the Hall of Fame. At worst, given the possibility that these clubs aren’t just duplicates of his old set stamped with McLaren on them, he’s made an equipment change that would take time, and 45-year-old athletes don’t have the time to do such things.

Gianni: Aronimink has only hosted a handful of professional events since it hosted the 1962 PGA Championship. What kind of test does it present, and does a course with less recent major championship history tend to level the playing field?

Brandel: Even though Aronimink has only hosted a handful of meaningful professional events, it has been fairly discerning in who can win there. When Keegan Bradley won the BMW Championship on the Donald Ross masterpiece in 2018, he was the 2nd best iron player on tour coming into that week. When Nick Watney won the AT&T at Aronimink in 2011, he was 2nd in strokes gained total coming into the week.

In 2020, Aronimink hosted the KPMG Championship, and Sei Young Kim won. On the LPGA that year, she was first in greens in regulation, putts per green in regulation, and scoring average on the way to being the LPGA player of the year. And then there is the 1962 PGA Championship won by Gary Player, who eventually became just one of a few players to win the career grand slam on the way to winning 9 majors. It is a formidable test, and if it’s not softened by rain, it will bring out the best in the upper echelons of the game.

Gianni: Is there a specific hole at Aronimink that you think will do the most to decide the winner?

Brandel: The hardest hole at Aronimink in each of the three tour events that have been played there since 2010 has been the long par-3 8th hole, with the par-4 10th being the second hardest, so most of the carnage will happen around the turn, but with the par-5 16th offering opportunities for bold plays and the tough closing holes at 17 and 18, the finish is likely to be frenetic.

Gianni: The PGA Championship has always sat in the shadow of the other majors. What does the ideal PGA Championship look like in your eyes, and what would it take for it to carve out its own identity?

Brandel: The PGA Championship, to whatever degree it suffers from the comparison to the other three majors, is still counted just as much when adding them up at the end of one’s career. Almost 1/3 of Nicklaus’ major wins were the five PGA Championships he won. Walter Hagen won 11 majors, five of which were PGA Championships.

Tiger Woods twice in his career won back-to-back PGA Championships, and those four majors count just as much as the other 11 he won. The PGA may not have the prestige of the other three, but it carries the same weight. Having said that, I preferred the identity that it had as the last major of the year.

Gianni: You nailed your Masters picks. Rory won, Scottie finished solo second, and Morikawa surged to a tie for seventh. Who are your top 3 picks for the PGA Championship and why?

Brandel: I am not a huge fan of majors played on golf courses that have been shorn of most of the trees, although I understand some of the agronomic reasons for doing so and of course the ease with which it allows members to play after errant drives. However, at the highest level, it all but eliminates any strategy off the tee and turns professional golf into an even bigger slugfest. That means that it will likely be a bomber’s delight this week, but fortunately, Scottie Scheffler is long enough to play that game and straight enough to play it better than anyone else.

The major championships give us very few surprises anymore, going back to the beginning of 2012, so the last 57 majors played, the average world rank of the winners has been better than 15th in the world. So look at the highest ranked and longest drivers who are on form coming into the PGA Championship who also have great short games as the surrounds at Aronimink are very challenging. That’s Scottie Scheffler by a mile and then McIlroy and Cameron Young with a far bigger nod towards DeChambeau than I gave him at the Masters.

In this episode of the Club Junkie Podcast, we dive into one of the most interesting flatstick releases of the year with a full review of the new TaylorMade SYSTM 2 putters. After spending time on the greens, I break down what makes this design stand out, where it performs, and why it has me completely torn between loving it and fighting it. If you are into feel, alignment, and consistency, this is one you will want to hear about.

We also take a look at some of the putters in play on the PGA Tour last week. From familiar favorites to a few surprising setups, there is always something to learn from what the best players in the world are rolling with under pressure.

To wrap things up, I walk through the process of building a set of JP Golf Prime irons paired with Baddazz Gold Series shafts. From component selection to performance goals, this is a deep dive into what goes into creating a unique custom set and why this combo has been so intriguing.

From 14 handicap to pro: 4 things I’d tell golfers at 50

Published

on

This year my 50th birthday. Gosh, where has the time gone?

As a teenager in rural Missouri, some of my junior high and high school years felt interminable. Graduation seemed light years away. But the older I get, the faster life seems to fly by.

I’m also increasingly aware of my mortality. My dad died recently. Earlier this year, a friend and fellow PGA of America professional and I were texting about our next catch-up. The next message I received was news of his unexpected passing at 48. Shortly after, a woman I dated in college succumbed to cancer at 51.

Certainly, one can share perspective at any age. Seniors help freshmen, veterans guide rookies. But reaching this milestone feels like as good a time as any to do one of those “what would I tell my younger self?” articles.

I’ve had a uniquely varied career in golf. I started as a 27-year-old, average-length-hitting, 14-handicap computer engineer and somehow managed to turn pro before running out of money, constantly bootstrapping my way forward. I’ve won qualifiers and set venue records in the World Long Drive Championships, finished fifth at the Speedgolf World Championships, coached all skill levels as a PGA of America professional, built industry-leading swing speed training programs for Swing Man Golf, helped advance the single-length iron market with Sterling Irons®, caddied on the PGA TOUR and PGA TOUR Champions, and played about 300 courses across 32 countries.

It’s been a ride, and I’ve gone both deep and wide.

So while I can consult and advise from a lot of angles, let me keep it to a few things I’d tell the average golfer who wants to improve.

1. Think About What You Want

Everyone has their own reason for picking up a golf club.

Oddly, as a professional athlete, I’m not internally driven by competition. That can be challenging, as the industry currently prioritizes and incentivizes competition over the love of the game.

For me, I love walking and being outdoors. Nature helps balance my energy. I prefer courses that are integrated into the natural beauty of their surroundings. I’m comfortable practicing alone. I’m a deep thinker, and I genuinely enjoy investigating the game, using data and intuition to unearth unique, often innovative insights. I’m fortunate to be strong and athletic, so I appreciate the chance to engage with my abilities. Traveling feels adventurous. I could go on.

You don’t have to overthink it like I do. For you, it might be as simple as hitting balls to escape work, hanging out with friends, and playing loosely with the rules and the score.

The point is to give yourself permission to play for your own reasons, and let that be enough.

But if improvement is your goal, thinking about your destination—and when you want to get there—is important, because it dictates the steps you need to take. When I set out to go from a 14-handicap to the PGA TOUR as quickly as possible, the steps I needed were very different from those of a working golfer trying to break 90 in six months. That’s also different from someone who just wants a few peaceful hours outside each week, away from work or family.

None of these goals are better than the others, but each requires a different plan that you can work backward from.

2. There Are Lots of Things That Can Work

One of the challenges of golf is that, although there are rules for playing, there aren’t clear, industry-wide standards for how to best play the game. There’s a lot of gray area.

You might hear a top coach or trainer insist that a certain move is the best way to swing or train. Then you dig a bit deeper and, much to your confusion and frustration, another respected coach or trainer says something completely different. I don’t think anyone is trying to confuse you—at least I hope not. It’s just where the industry is right now.

You have to be careful with advice from tournament pros, too. They might be great at scoring, but they’re also human and sometimes just as susceptible as amateurs to believing things that don’t really move the needle. Tour players might describe what they feel, but that’s not always what they’re actually doing when assessed with technology.

I recently ran a test on my YouTube channel (which connects to my GolfWRX article “How to use your hands in the golf swing for power and accuracy”), and, interestingly, two of the most commonly taught hand actions produced the worst results in the test.

Coaches can certainly help. If you find someone you connect with to help navigate, that’s great. But there are many ways to get the ball in the hole. In the current landscape, you may need to seek multiple opinions, think critically, and use your own intuition to discern what seems true and whose advice resonates with you.

I’d recommend seeking someone who is open-minded and always learning, because things constantly change. Absolutes like “correct” or “proper” should raise a red flag. AI can be useful, but it tends to confidently repeat popular advice, so proceed with caution.

3. Get Custom Fit

If you’re serious about becoming a better player, getting custom fit is hugely important. There’s no sense fighting your equipment if you don’t have to. Most better players get fit these days and, if they don’t, they’re usually skilled enough to work around clubs that aren’t ideal.

If you plan to play for a long time, it’s worth spending a little more upfront to get something that truly fits you and your game, rather than continually buying and discarding equipment.

Equipment rules haven’t really changed significantly since the early 2000s. To stay in business, manufacturers keep pushing those limits. If you pull a bunch of clubs and balls off the rack and test them, you’ll find differences. I’ve tested two new drivers and seen a 30-yard total distance gap. Usually, the issue isn’t bad equipment; it’s that the combination of components simply isn’t the best fit.

It’s like wearing a new pair of floppy clown shoes. Sure, they’re shoes—but you won’t sprint your best in them compared to track shoes that fit perfectly.

Be wary of what’s called custom fitting, too. Sometimes the term is used as a marketing strategy rather than an actual fitting. In some retail settings, fitters may be incentivized to steer you toward higher-priced components. That doesn’t automatically mean it’s not the best fit, but you should be aware of potential biases.

I learned a version of this lesson outside of golf. Years ago, I bought a tennis racquet at a big box store from a seemingly knowledgeable employee who thought it would suit me best. The racquet gave me tennis elbow, and I spent months recovering with rest and acupuncture. The next season, I invested more time and money to find what actually fit me, and I walked away with something amazing that I still play with years later.

So if you’re going to get fit, be smart about it.

Find someone you believe has deep knowledge—possibly with certifications, but not necessarily. Make sure there’s a wide inventory across many brands. Check recent reviews for the individual fitter if possible. Make sure you trust that the fitter has your best interests at heart. If they’re wearing a hat or shirt with a specific brand’s logo, proceed with caution. Unless you specifically want a certain brand or look, be wary of upsells, especially if two options perform nearly the same.

Also, while golf is called a sport of integrity, there’s a thread of manipulation in the industry. I once drafted an equipment article for an industry magazine, structured just like one of their previous popular stories, with matching word count and great photos. The assistant editor loved it; it was useful to readers and required little work on his part. But the editor-in-chief nixed the story. When I asked why, I was told it was because I wasn’t an advertiser. It turned out the article I’d modeled mine after was a paid ad cleverly disguised as editorial content.

I really dislike games, clickbait, and fear-based manipulation. I hope this changes, but golfers deserve to know it exists.

4. Distance and Strategy Matter

There’s a real relationship between how far you hit the ball and your scoring average, even at the PGA TOUR level.

I experienced this early in my pro career. I started as a power hitter, swinging in the high 120s and breaking 200 mph ball speed with a stock driver.

Back then, some instructors advised swinging at 80%, so I tried slowing down for more accuracy. That worked fine on shorter, tighter courses. But on longer setups, I was coming into greens with too much club, and par 5s stopped being
