UST Mamiya Proforce Shaft Wins Buick Invitational

FORT WORTH, Texas — Feb. 9, 2009 — Coming down the wire on a fabled course well-noted for producing dramatic conclusions, high performance golf shafts designed and manufactured by UST Mamiya® continued their winning ways on the PGA Tour with a victory at the Buick Invitational at Torrey Pines Golf Club. This year’s champion trusted a UST Proforce V2 Tour Hybrid shaft (104 grams) in his 21-degree Titleist hybrid club to deliver superior consistency and accuracy to hit one of the most important shots on Sunday, a 235-yard shot with his hybrid from the par-5 18th fairway that easily cleared the green-side pond to put him into position for a two-putt birdie, and eventually secure the win.

“Accuracy and distance control were the two most important criteria when UST pioneered the hybrid shaft category with the introduction of the IROD Hybrid, then followed with Proforce V2 Hybrid, and at the beginning of this year introduced the Proforce AXIVCore Hybrid shafts,” says Jim McIntosh, director of tour operations for UST Mamiya. “The IROD Hybrid and Proforce V2 Tour Hybrid 89 and 100 have been favorites among tour pros, and we are excited to start testing the Proforce AXIVCore Hybrid in the heavier weights – AXIVCore HY 100 Black and 100 Red – in the coming weeks in a variety of OEM hybrid clubs.”

The new Proforce AXIVCore Hybrids integrate a true weave — four-axis material — within the inner walls (shaft core), providing stability and consistent recovery at impact — a design which makes the AXIVCore shafts unlike any other shaft in the world. This unique counter-balanced shaft also reduces club heft that helps players generate more club head speed which translates to more ball velocity and greater distance.

AXIV Technology in the Proforce AXIVCore Series is a UST Mamiya exclusive, proprietary process of weaving specific high-modulus carbon fibers in the critical four axis directions necessary in shaft design to optimize stiffness, hoop strength, and torsional resistance. The shaft resists deformation and returns the shaft to a round shape faster than other shafts on the market. The Proforce AXIVCore Series features a Blue, Tour Black and Tour Red models, and will be available in multiple weights and flexes to fit various swing profiles.

High performance UST Mamiya graphite shafts are trusted by some of the world’s top players, including UST Mamiya staff players Stewart Cink, Davis Love III and Rod Pampling.
