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.

Honma launches new XP-1 Series driver, fairway woods, and hybrids for 2020

Published

on

new 2020 Honma Driver

For 2020, Honma Golf is launching the all-new XP-1 line of clubs comprised of an entire family holistically designed to help players maximize forgiveness and get the most out of their games with one set. The new Honma XP-1 drivers, fairway woods, and hybrids, all the way to irons, is a new direction for the premium Japanese company that brings together ultimate craftsmanship with performance.

The highlight of the XP-1 line from Honma is the fact that they were designed from top to bottom to work as a comprehensive set of tool to achieve maximum performance. The technology in the metal woods flows from the driver to the hybrids with a seamless transition that creates consistency for feel and looks for the player.

Honma is known for its dedication to quality and craftsmanship, and every part of the XP-1 line was developed with the golfer in mind to both look appealing and perform to the highest standards. The XP-1 driver packs a lot of technology into a very classic looking club, and we’re here to take you under the hood—or in this case, the carbon fiber crown—to show you how it can help you hit better shots.

It starts with a tour-inspired look from address, designed to inspire confidence for any level of golfer. Underneath ther gloss black crown, there is a lot of technology to generate faster ball speeds around the entire face and help get you dialed into the right setting. Speaking to the crown, it’s made from ET-40 fiber, making it one the lightest in golf. This weight savings helps engineers relocate an additional 15g of mass around the head towards the heel for increased MOI and greater ability to help players close the club face more easily.

Flip the driver upside down, and we have a lot more going on with the sole than initially meets the eye. Honma is introducing a new double slot in the sole for increased ball speed across a much larger area of the face. What starts off smaller in the middle increases in width and depth as it reaches towards the heel and the toe of the club. These slots, along with improved MOI, keep ball speeds up and misses closer to the intended target. The last part of the equation: How these wider parts of the face, flex around the more narrow middle to also increase gear effect—think of it like one more way to help the bigger misses stay in play.

The last piece key piece of technology in the XP-1 driver head is exclusive to Honma—the adjustable hosel that changes face angle, lie, and loft, but never changes the orientation of the shaft. This gives the player or fitter the ability to truly dial in hosel settings without having to worry about the constantly changing of the grip orientation. This, according to Honma, also keeps the shaft spine in the ideal location for consistent performance.

Honma is the only manufacturer that produces its own shafts from start to finish in house, and the XP-1 is getting its own custom-designed and built shafts to complement the technology built into the heads. The Vizard stock shafts are engineered to produce a smooth feel that promotes faster clubhead speeds, yet also remain extremely stable. For the XP-1 driver, the matching Vizard shafts will come in weights of 43g, 53g, and 63g, and flexes from senior to stiff.

Honma XP-1 fairway woods

The XP-1 woods bring the same level of craftsmanship and technology as the drivers to a club designed for use both off the tee and off the fairway.

The Honma XP-1 3-wood uses the same weight-saving ET-40 crown to position a large amount of the club’s total mass low and on the sole for greatest possible launch and spin consistency. The 3-wood is the second-lightest club in most players bags by total weight and head mass, and unless you are carrying a second driver, it’s also the second-largest by volume. By using the carbon crown designers get everything they can from the other technologies including the double slot sole and thin fast face without having to sacrifice the overall design of not just the head but the entire club.

The XP-1 fairways also include a 5  7-woods, but with the smaller volume of the heads and the reduced crown size, using a carbon crown would actually increase the mass higher in the head, so they instead utilize an extremely thin high strength steel crown.

All of the fairway woods come with the same made-in-Sakata, Japan 43g, 53g, and 63g Vizard shaft options as the driver to help every player get the most of each club in the set. If might seem like a minor detail, but being able to design an entire club in house from head to grip is a big advantage for Honma versus other OEMs. This holistic approach to designing an entire club/set is a big benefit to the consumer looking to get the most out of each club in their bag and not feel like something may be working against them.

Honma XP-1 hybrid

With the Honma XP-1 hybrid, forgiveness and flow from the fairway woods is the number one consideration for these club. The flow includes a wood-like shape that keeps the club shallow and the center of gravity as low as possible for higher launch and approach shots that fly higher and land softer. Considering the target player for the XP-1 line, the wood-like shape is also very confidence-inspiring.

Honma continues the design philosophy of keeping the XP-1 both forgiving and fast by utilizing the double slot sole all the way into these hybrids that go from a 19-degree 3-iron replacement to a 25-degree 5-iron replacement.

Honma XP-1 specs & availability

The Honma XP-1 driver, fairway wood, and hybrids will be available starting in October.
