Inside info on Jason Dufner’s custom LA Golf Shafts long iron shaft

Published

on

This week, on the range at the Military Tribute at The Greenbrier, the inaugural event of the 2019 – 2020 PGA Tour season, we spotted Jason Dufner with a very custom LA Golf Shafts long iron shaft.

We reached out to LA Golf Shafts Chief Product Officer John Oldenburg to get the inside info, and John did not disappoint in the details and the story behind the switch by Jason.

“Duff reached out to me shortly after he put our new OLYSS 65 Tour X prototype in play in his driver last season.  He was looking for something for his 4-iron that would get the ball up in the air a bit easier, but maintain (or increase) distance, and keep the spin close to where it was with his existing shaft which was a TT Dynamic Gold AMT S400.  What I worked on providing him was a shaft that had an overall stiffness/frequency and weight that were comparable to his current set up, but with a softer tip section.  And to improve accuracy (decrease dispersion), I wanted to get him something with lower torque than the TT AMT shaft.  So, in a nutshell, that’s what I designed for him.  It’s a 125 gram shaft with a frequency close to the AMT S400, but with a tip that is pretty significantly softer and has 0.3 degrees lower torque.  The combo of a softer tip with lower torque will help him to launch the ball higher but maintain his accuracy.  The “Duff 4-iron”, also has a higher balance point than the AMT S440.  That way Duff can use a heavier head, get the same swingweight he is comfortable with, and put a little more mass behind the ball at impact to get an increase in ball speed and thus distance.”

“That’s the great thing about graphite.  The limitless design capability.  Graphite is a huge family of composite materials, with different stiffness, strength, density, etc..   Steel, although there are more alloys available today, is primarily a single material with a defined, limited set of mechanical properties.  And even with the additional alloys, individual steel shafts are made from one single steel alloy.  I can mix and match any number of composite materials into a single shaft, to change, enhance, fine tune any number of the shaft playing characteristics.  I can lower the torque and soften the tip.  With steel, if you soften the tip, the torque has to go up.  With steel, change the weight and you change the stiffness and torque.  Composites allow me to adjust individual attributes while having little or no effect on the remaining attributes.  This is a huge benefit of graphite and one of the reasons that I am working with Bryson and Duff and complete sets of graphite for their irons.  Stay tuned!”

This hopefully answers some of the questions that have been asked in the forums about a potential full iron set, and thanks to John we can look forward to more individual player-focused products.

    Too bad this isn’t available to the average consumer.

Forum Thread of the Day: “Kiradech Aphibarnrat’s custom SuperStroke grips”

Published

on

Today’s Forum Thread of the Day showcases Kiradech Aphibarnrat’s custom SuperStroke grips. The shape of the grips has been given the seal of approval from WRXers who have been keenly discussing the SuperStroke creations in our forums.

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.

  • JCM96: “Love SuperStroke’s texture and feel. If they would just release their tapered grips, they’d get a stranglehold of the putter grip market.”
  • jgolf215: “Interesting shape. The colors are pretty understated for him. I would have expected a much brighter green.”
  • nova6868: “Really like the shape on those. Would definitely buy one if they were available.”
  • GoIrish17: “What’s it say? SGP1.0? I like the shape of it; I hope it comes to retail (or SuperStroke sells them through their eBay store). It looks like a grip I’d like to try.”

SeeMore Putter

Today’s Forum Thread of the Day showcases an array of new SeeMore putters. The new flat-sticks from SeeMore have been a hot topic for discussion amongst our members, with the brand’s plumber neck additions garnering plenty of reaction.

For lots more photos, check out the full forum thread here.

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

  • bunta: “The fact that they put the alignment line on the topline of the Ancers makes me feel obligated to give them a try.”
  • poppman2142: “So the plumbers going into the head at such a severe angle is making them face-balanced I assume? I guess I would prefer the hosel to angle towards the center of the face and have the shaft angle back where it enters the hosel, so I don’t see the entire length of the hosel at address to make it face balanced. To each their own I guess!”
  • MaineMariner: “Those are some very interesting and unique hosels. Gotta hand it to SeeMore, they sure are innovative. I could definitely see myself grabbing that plumber’s neck notchback.”
