The GolfWRX forums exist so golfers have access to the latest equipment releases, hottest discussions, real equipment reviews, best instruction, new technologies and everything golf you can imagine.

So if you love golf, the GolfWRX forums are your sanctuary.

In the From the Forums weekly feature, we bring you the hottest, most buzz-worthy topics from our forums for your convenience. I’ll be your trusty tour guide to navigate the latest buzz.

Here’s a peek behind the curtain into golf’s sanctuary. 

Charles Howell III with new PXG “Mustang” putter at 2015 Barclays

As Andrew Tursky wrote in his “11 Revealing Photos from The Barclays:” Charles Howell III “seems to have a new gamer putter every week, and he’s usually tinkering with at least two other putters … This week he’s testing a few PXG putters, and last time he teed it up at the PGA Championship he was gaming a Scotty Cameron prototype. As gear heads we should all have sympathy for him; he’s truly one of us.”

We got some great shots of the Georgia native’s new weaponry. And like all things Parsons, this Mustang is a unique-looking putter.

Funeral arrangements for Tiger’s golf life

U.S. Open - Fourth Round

User shoeman started the thread with this post, motivated by Tiger Woods’ triple-bogey seven and fall from contention during the final round of the Wyndham Championship.

“It’s time to put a end to all hopes & dreams for TW! One of the weakest field ever & the results were zero wins for TW 2015! Tigers’ golf life ended on August 23, 2015, on the 11th hole! The cause of death reported by the coroner–asphyxiation!!  It’s time to move on from Tigers passing! Once you accept his golf life death, the better off you will be!”

Another user offered this counter, however: “Did you stop watching after 11? Tiger had 4 birdies coming in. I think he is alive and well. He made some mistakes, but he made some progress, also.”

There have been 85 replies to the topic in just three days and the debate is…spirited. If you (like seemingly all golf fans) have strong opinions about the Big Cat, you might want to weigh in.

U.S. Amateur is painful

2015-SMU-DeChambeau-NCCA-Men-1071_t780

Bryson DeChambeu’s, shall we say, “deliberate” play en route to winning last week’s U.S. Amateur raised some eyebrows. The SMU student wasn’t exactly playing speed golf.

User dpatti wrote:

“I’m watching the Amateur and this guy Dechambeau could be the slowest player I’ve ever seen. Don’t get me wrong he’s a great player and I’m sure a good guy but he’s got to be miserable to play with.”

Did you watch the Amateur? Think DeChambeau should be renamed DeChamb-slow? Think the problem extends beyond Bryson to college golf or amateur golf in general?

Can somebody give me the simple or scientific reason why…

You’ll find many of the members in our “Instruction & Academy” forum know a bit more about the golf swing than the talking heads on television.

Check out this thread in which Mizunogolfer asks why a driver swing is longer than a six-iron for most golfer and iteachgolf takes on the task of replying (you may want to brush up on your principles of physics first).

Mizunogolfer: A driver swing is longer than a 6 iron swing for most people

Definitely the case for me, on a full hard drive and a full hard six iron my backswing is longer with the driver

iteachgolf: Driver creates the highest club head speed in the backswing as well as downswing. Therefore faster moving club head creates more inertia making it harder to change direction. This resistance to changing direction leads to the swing to be longer. Also factor in human reaction time staying constant while club is moving faster will also make it take longer to stop and then change direction

mizunostaffer: Why is this?

“I’m going to need a better explanation of why you think a driver has more inertia than a 6 iron. The formula for inertia is

F=mass * acceleration

For a rotating body it’s

F=mr*r (mass * R squared)”

The mass of a driver is actually LESS than the mass of a 6 iron.  Yes, the driver is longer, but the head is lighter (hence the whole “swing weight” calculation).

iteachgolf: So to keep it simple the radius is squared. Therefore the significant change in radius would have a larger effect than the lesser change in weight.  6 iron weight 50-70 grams more than a driver (lots of variables). So the R^2 of a 6 iron vs driver is more than a 50% increase (1,406.25 vs 2,116).  The difference in weight between a 6 iron and a driver is roughly 20-30%.  So the change in radius has a much larger impact even though it has less weight.

Well that got scientific (or mathematic) real quick!

    “Well that got scientific (or mathematic) real quick!” And your point is??? Hey, it’s a technical question and REQUIRES a technical answer.

    I don’t agree with iteachgolf; mizunostaffer is closer, but still not spot-on. Here’s the problem. Let’s start by accepting iteachgolf’s assertion that the problem is changing the direction of the club at the top of the backswing. (I don’t think it’s correct, but let’s see where it leads.) The change of direction is of a club moving backward to moving forward, but not much rotation involved, no faster than the rotation of the arms and body. Therefore, most of the radius involved is the arm/shoulder stretch, which for the same golfer should be the same for both clubs. Relatively little radius difference is the club length at this point in the swing.

    So it’s mostly a mass difference. And the mass ratio is 33%, bigger than the 20-30% that iteachgolf asserts. Here are my calculations — head plus shaft plus grip:
    6-iron: 263+100+50 = 413g (shaft between 80g graphite and 120g steel)
    driver: 200+60+50 = 310g (graphite driver shaft)
    ratio = 413/310 = 1.33, or 33%

    If we assume that we want the moment of inertia, not just the mass of the club, let’s see where that leads us. We will need a radius. Let’s assume an arm length of 24″, we compute a 6-iron balance point at 28.9″ and a driver balance point at 34.0″. Assuming a 90* wrist cock at the top of the backswing, the radius r is 37.5 for the 6-iron and 41.6 for the driver. That gives an r-squared ratio of 1.23 or 23%.

    My conclusion: if the explanation were the difficulty in changing the club’s direction at the top of the swing, the 6-iron swing would be longer. But the driver swing has been observed to be longer. Conclusion: difficulty of changing the direction of the club is not a viable explanation.

    Yeah, this should probably be posted in the thread, not this summary article, but I’m lazy.

    Many years ago, I use to attend the Danny Thomas St. Jude Classic, now the Fedex St. Jude. When Gil Morgan was a regular on the PGA tour, he would come over and play in Memphis. I probably went for 10 straight years, and every year, more than one person would always come up to me and ask me if I was Gil Morgan’s brother. It was mostly tour players who would approach me and ask me if I was Gil Morgan’s brother. I would tell them no and then ask them for their autograph!

    I learnt that f=m*v*v/r . Does that mean are error above?

Srixon ZXi combo or TaylorMade P7CB/770 combo? – GolfWRXers discuss

Published

on

In our forums, our members have been pitting a Srixon ZXi combo against a TaylorMade P7CB/770 combo. WRXer ‘edutch22’ is on the hunt for a new set of irons and kicks off the thread saying:

“Looking at picking up a new set of irons and think I’ve narrowed it down to Srixon ZXi combo or Taylormade P7CB/770 combo. I am currently a 5 cap and allbeit I feel irons are my weakness. My miss is a little to the toe side. I am decently steep at 4-5 down. Always thought I am high spin but recently on trackman my 7 was spinning at 5800 roughly. 

My question or looking for thoughts on which one would benefit me more from a forgiveness standpoint? Or is there another iron is should be looking at entirely? I only get to play about once or twice a week, if I am not playing a 2-3 day event. Thanks in advance.”

And our members have been sharing their thoughts and suggestions in response.

Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

  • manima1: “You just can’t go wrong with Srixon ZXi7.”
  • MattM97: “You have to hit them to know, the V-Sole on the Srixon can be make or break for many.”
  • dmeeksDC: “P7CB is more forgiving for me than ZXi7 because my main miss is low middle and the P7CB still flies and spins great on that miss. These are both really nice irons but I like the P7CB more than the Zxi7 and the P770 (or P790) more than the Zxi5. The Srixons are larger so if that gives you confidence that is the way to go. I don’t feel like I get any benefit from the V-sole and the P7CBs live up to their high Maltby forgiveness rating so the TaylorMades have been great for me.”

Mizuno Pro M13 vs Callaway X Forged: My actual fitting numbers – GolfWRXers discuss

Published

on

In our forums, our members have been reacting to a fitting session involving Mizuno’s Pro M13 and Callaway’s X Forged irons. WRXer ‘careergolfer’ recently went through a full fitting session and shared his numbers and commentary, saying:

“After playing Callaway Apex Pros for the pats 5 years, just went through a full iron fitting and thought the data was interesting enough to share. I’ve seen a lot of posts talking about fittings but not many with actual numbers, so here’s mine.

All 7-iron, same ball, same session. Final two were the ones I was choosing between:

Club Ball Speed Launch Spin Side Angle Carry Total
Current irons 121.1 mph 18.3° 6,691 rpm 0.7L 170 178
Callaway X Forged 125.8 mph 15.9° 6,144 rpm 2.2L 180 185
Mizuno M-13 125.8 mph 17.9° 6,638 rpm 2.2L 177 182

The consistency numbers are what actually made the decision:

Club Ball Speed SD Spin SD Total Yards SD
Current irons 3.3 294 5
Callaway X Forged 2.0 211 3
Mizuno M-13 1.1 150 2

Callaway won on distance by 3 yards but got there with a much lower ball flight (15.9° launch, 6,144 spin). The Mizuno matched my existing flight profile with nearly 3x tighter ball speed consistency.

Fitter also noted I’ve been setting up with a closed face at address to compensate for a heel-heavy dynamic lie. Ordered the M-13s 1° flat to bring impact back to neutral: the theory being if I can set up square, I can actually commit to the release. I’m not sure if this was the right call TBH but took the fitter’s guidance. I’ll see what happens.

Went with the Mizuno. Clubs aren’t in hand yet. Happy to share follow-up data once I’ve played them!”

And our members have been sharing their thoughts in response.

Here are a couple of posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

  • PowerCobra98: “M13 certainly performed well.  Enjoy the new irons once you get them!”
  • dmeeksDC: “Two completely different irons. The X Forged is a tour-type iron and would match up with the S3 in the Mizuno lineup. Not going to see a lot of M-13 on pro tours. It’s a crossover iron, three different types of construction in the same set. The M-13 would be more like the AI 150 as the M-13 7 iron is a half-hollow club versus X Forged, which is a straight up forged iron. M-13 middle irons have very thin faces, not holding up well for some buyers if you read through the M-13 thread. Hopefully Mizuno has corrected it. Given the differences in construction, that is surprising ball speed with the X Forged. To me the numbers are quite an endorsement of the X Forged considering it has no ‘tech.'”

Has there been a better driver since this Ping release? – GolfWRXers discuss

Published

on

In our forums, our members have been discussing drivers. WRXer ‘Ty-Webb’ is still playing Ping’s G400 LS driver and reaches out to fellow members saying:

“Playing the G400 LS still and wondering if newer is any better? For someone who thinks golf equipment is 90% marketing, change my mind.”

And our members have been weighing in with their top picks in response.

Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

  • meliaant: “As someone who graduated from the OG SIM to the Qi10, I can you two things: 1) on-center hits are essentially identical. 2) off-center hits are wildly, absurdly better with newer drivers.”
  • Golfingfanatic: “I went from the G400 to the GT2 – probably a wash distance wise from the sweet spot, but much better at handling spin off-center.. would definitely try some new stuff if you can.”
  • bluedot: “Given the number of heads and shafts that are available, plus the fact that you’re talking about a 9 yr old club, plus the available fitting technology, the answer is almost certainly yes.  Add to that the fact that the Ping LS models are sort of ‘specialized’ drivers, as are the Ping SFT’s; heck, you might need MORE spin! How much better is really the question, and that depends on how well suited the G400 LS is to your swing, and how you will go about finding an alternative.”
