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

Published

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.

Why Ben Griffin is making the surprising switch to a Maxfli golf ball

Ben Griffin might be a little too young to remember some of the iconic Maxfli golf balls that won on tour, but that isn’t stopping him from putting the newest Tour X ball from the brand in play. Today, Maxfli and Griffin announced an exclusive partnership that will see the PGA Tour player using the company’s four-piece golf ball.

While Griffin might be the first PGA Tour player to put a new Maxfli golf ball in play, he isn’t the first profesional golfer to do so. Lexi Thompson has been playing the Maxfli Tour golf ball on the LPGA Tour since the beginning of the 2024.

A post shared by GolfWRX (@golfwrx)

We caught up with Ben at the CJ Cup Byron Nelson in Texas this week to ask him about the new ball switch.

“I was able to finally get my hands on some and try it and immediately I saw faster ball speed with the driver, which is always something every golfer wants to see.

“Then I had to test a lot around the greens and test irons, test spins, test everything like that. Basically, I came to the conclusion that I thought this was probably one of the best golf balls for my game.

“And so I decided to make it official and partner with them and very excited to help kind of launch this golf ball and see where it takes us.”

Griffin’s ball of choice is the Maxfli Tour X, a four-piece golf ball that is made for highly skilled players that want consistent distance off the driver and spin around the green. An updated core design helps add the ball speed that Griffin mentioned and two ionomer mantle layers separate low spin driver shots from higher spin iron and wedge shots. Maxfli uses Center Of center-of-gravity balancing to ensure each ball has consistent flight in the air and roll on the green. Like all golf balls on tour, the Tour X features a cast urethane cover for maximum performance, and it has a tetrahedron dimple pattern to enhance aerodynamics.

It is exciting to see a golf ball at a lower price point — $39.99 at Golf Galaxy — being used by a top 100 ranked player in the world like Ben Griffin, and equipment junkies will be keenly watching his performance with the new ball.
