TXG: Does shaft weight and torque matter?

Published

on

We’re excited to announce a new video partnership with Tour Experience Golf, a Custom Golf Club Fitting Studio in Toronto, Canada. Check out the announcement video here for more information.

In the first video, TXG isolates shaft weight and torque as the only variables in a club test to see how those factors influence delivery and ball flight. Check out the video below, and let us know in the comments what topics you’d like covered next time!

    The discussion of shaft weight is solid, but misses the point. Each player, as shown in the discussion, has a “felt weight” that matches his swing. That “felt weight” can be measured as dynamic moment of inertia. If the player hits at his best MOI, he will have the most consistent swing and best probability of center face strikes. If that MOI is measured from a point between the hands (typ about 4″ from the butt), the entire set of clubs can be matched to that MOI and the player will be more consistent throughout the set.

    In the case of the player tested for the video, the middle weight shaft resulted in his best MOI match.

    On a related subject, we need to see fitting discussions related to the real (non-professional) world. I need to better fit my 220-230 yard driver swing, not drool over a 300 yard bomber.

    It’s mostly snake oil. You need to be a tour caliber player to see any benefits.

    My girl says it’s always about the girth and heft

    It is great to test isolated variables to see the affects and how to fit properly. Weight definitely affects the golf swing in terms of tempo. However, I disagree that weight was the root cause the inconsistency with the test results. To me, it was the torque that caused most of the inconsistency in the dispersion of the groupings.

    The guy on the right thinks that torque is only a “feel” variable and doesn’t think torque affects the dispersion because impact is too short of time frame for the club to twist to cause an off line shot. I totally disagree because twisting of shaft does not just occur at impact. Twisting of the shaft occurs throughout the golf swing. So, throughout the golf swing the clubhead will be twisting depending on the player’s golf swing. Therefore, the clubhead could be off a few degrees off at impact because the clubhead was twisting on the downswing.

    Generally speaking, the higher the torque will cause a strong swinger to spray shots more than a tighter lower torque shaft. To me, there is generally a sweet spot for a torque for each player depending on how much player influences a shaft. Torque definitely affect dispersion.

      The clubhead not only twists the shaft, the shaft tip “droops” so the clubhead CG aligns with the shaft axis. This closes the driver club face for impact. During impact the clubhead kicks back for a few microseconds before it launches the ball. Shaft flex is complex.

        Shaft flex is complex because there is so much variation in flex patterns. However, I would bet if you compared a same weight shaft to the one in the test (where he was spraying his shots) with another shaft that has around a point lower torque, the dispersion would be tighter. I have done that test several times over the years. I truly believe there is still a torque sweet spot for players that enables them to release the club more squarely through impact.

    These guys are the best fitters period. Watch there videos. Hi Im 66 and 85-90 mph and for my quick tempo swing i play a 330 gram driver, 64 stiff diamana r series midsize grip callaway fudion head 10.5 with 14 gram weight at 45 and st club championi tried everything head snd shaft and nothing beat it. Lighter is not faster for quick swing. For je weight anf torque first.

      330 gram driver must be total weight because driver heads are in the 200 gram weights. You are correct that how you load your shaft is more important than shaft weight.

    Not as much as a good or bad swing matters…

    Do shaft weight and torque matter?
    Yes they do

    Have you ever done any testing with multiple versions of the same shaft to see differences in manufacturing?

    Those cpm ratings are all just measured at one spot right? Cause couldn’t the shafts have different stiffnesses (cpm ratings) throughout the rest of the shaft even though they all are the same stiffness in that spot?

    Good stuff. How do you look at fitting a slower swinger…I’m 74, play the Epic Star and am always looking for more distance. My carry distance is ~ 220 yds, relatively high ball flight. Swing speed in ~85-90 mph. Always thought r flex, lighter shaft and relatively high torque. Does this match with your studies? Thanks…/JV

      Hi Joe, it sounds like if you’re swinging it at 85-90 and getting 220 carry, you’re doing pretty well. Realistically, it will be pretty difficult to get much more out of it. Especially by playing about with shafts. At the end of the day, club head is the most important thing. Don’t let anyone tell you different.

      What is your driver face loft? 10º? 12º? 14º? You may get more distance with higher lofts to match your lower swing speed.

WRX Spotted: A pair of custom putters

Published

on

This week’s Zurich Classic is all about pairs — that goes for the two-man teams competing for the winner’s check(s), and in the case of notable putters we spotted, a pair of new one-off customs in bags this week: Abraham Ancer’s personal Bettinardi and Danny Lee’s new Scotty Cameron Super Rat.

Let’s start with the Danny Lee’s because there is a LOT going on with that club including first and foremost – it’s one nasty wand:

  • Super Rat head shape with a single sight line
  • The milled (actual) loft appears to be pretty standard for Cameron Putters
  • The hosel has been bent to accommodate Danny’s “armlock” style. This keeps the loft of the head where it should be while forward pressing. This kind of adjustment would need to be made to any standard putter if you were to try the armlock, or else you would deliver negative loft at impact
  • The shaft is LA Golf Shaft OZIK TP — a shaft designed to remove undesirable vibration through the shaft, while also reducing putter head oscillation at impact. Not a surprise considering the number of multi material/graphite putter shafts that are available right now to help improve consistency.
  • Last but not least a SuperStroke Flatso grip installed with the flat part of the grip aligned parallel to the putter face! This isn’t the first time we’ve seen something like this, and it makes sense – Utilizing the orientation of the grip to create greater awareness of the face angle can help players of all skill levels create more consistent results, even tour pros.

Danny has had an interesting golf bag to follow this season with a number of changes coming almost weekly from irons to putters. Maybe this change could help turn his putting around (currently ranked 116th in strokes gained: putting), all while still being inside the top 50 in the FedEx Cup.

Now to Abraham Ancer’s new Custom DASS BBZero Tour Dept. Putter.

  • This putter is based off of the BBZerostyle head with rounded bumpers and a plumbers neck
  • Compared to the BBZero though, the heel is thicker and it could have a slightly shorter blade length (TBD)
  • It has a recessed sight line on the top that runs perpendicular to the sight line in the flange to form a “T.” This is interesting for a couple of reasons including that it looks to be the width of a golf ball, which could help Abraham find the center better. Also as a right-handed golfer, this type of alignment is an indication that he is most likely right-eye dominant and uses the face of the putter to align to the target as much if not more than the flange line.
  • Just like Danny’s above, this putter is also shafted with the LA Golf Shaft OZIK TP — there must be something about that that has more players testing it out.
  • And finally, the grip is the SuperStroke Claw. Judging by the cleanliness of both these grips these are both new to the players and testing will prove what ends up come tournament time.

Forum Thread of the Day: “Iron type for controlling shots into the wind?”

Published

on

Today’s Forum Thread of the Day comes from eckmanjp who is on the hunt for irons to help with controlling shots played into the wind. Our members give their opinions on what are the best options for eckmanjp, with plenty of different clubs and shafts recommended.

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.

  • driveandputtmachine: “Into the wind, spin is NOT your friend. No matter how low launching it will balloon. I was an extremely high spin player, in my search for something lower spinning my three best were…. TM P 790, Cobra Forged TEC, and Ping i500.The final piece is a shaft that spins high enough to hold greens, but not too high to balloon into the wind.”
  • mogc60: “Sounds like you have good clubs and shaft combo for reducing spin. Shafts do make a difference…but don’t cure the upshoot into the wind. Good advice above about more club and swinging slower…speed equals spin. I find the biggest mistake people make into the wind is playing the ball too far back and hitting down too hard. The key is smooth through impact and finishing low in your follow through…not pounding it down…that creates that upshooting shot that the wind destroys.”
  • dpb5031: “Technique plays the major role here, not equipment. Generally, anywhere from 1 to 3 extra club, grip down on the handle, and use what I call a wide-to-wide swing at 3/4 speed. Think limited arm swing (no longer than left arm parallel with the ground in BS) and then cover the ball, keep body turning through it, and finish wide & low, with handle following your rotating trunk around to the left.”
  • rxk9fan: “I think the head/shaft combo can make a huge difference of course along with how you deliver the clubhead into the ball. Take a look at the Titleist shaft chart and see what they are showing. FWIW though, the OP’s current shaft should not be a high launch/high spin shaft. I found both the 716 AP2 and CB to be tough to control spin with, but as suggested it was 100% my delivery at impact. I found the Srixon Z9xx series to spin less but the best thing I did was get to a quality teacher, and we improved a pretty tiny swing flaw that had a big impact on spin. Good luck. I can say I tried to “new club” my way through the spin problem, but three lessons is what it took to fix it.”

WRX Spotlight: Dead Zero Putting Disk Pro

Published

on

Product: Dead Zero Putting Disk Pro

Pitch: From Dead Zero: “The new Dead Zero Pro model putting disk offers golfers the ability to accurately determine green slope and a true fall line when practicing their “money” putts thanks to a bubble level embedded into the top of the disk. The bubble level accurately measures up to six-degrees of slope and gives a true reading of the fall line on any area of the putting surface. Like the Original model, the Dead Zero Pro helps all golfers build confidence to make more putts inside eight to ten feet.”

Our take on the Dead Zero Putting Disk Pro

The Dead Zero Pro Putting Disk Pro improves upon the original design by incorporating player and instructor feedback to include a level in the top of the disk. It’s a wise addition to a device that already offers players aid in an important practice approach: putting to a target smaller than the 4.25-inch cup. (The disk is roughly half the size)

We tried the Dead Zero Putting Disk Pro in the manner creator Eric Schmitt suggests in the video below.

We found it easier to focus on putting to a smaller target when using the device–the fact that the disk looks like a target certainly doesn’t hurt this! It’s also easier to practice breaking putts with the Dead Zero Putting Disk.

The level function helps quickly get an accurate feel for the putt, and you can set the disk down where the hole effectively “is,” from an aiming standpoint, on, say, an eight-footer that breaks six inches right to left.

It’s also a nice tool to have in your bag any time you need a target in practice, really, and are struggling to visualize a line or landing area. For example, when pitching from around the green.

Ultimately, this is a good practice and practice round tool that nicely functions as a smaller-than-a-golf-hole target for putting, a level, and an easy-to-see target.

A final word: There is something to the fact that golfers, particularly those who struggle with their putting, get hung up on aiming at a portion of the hole, “three balls out,” etc. If the cup has started to look more like foe than friend, shaking things up with a device like the Dead Zero Putting disk is recommended.
