Had a fitting todat to look for some extra yards in my long game. Gamer driver was a TSR2 (A1) Fujikura TR Red. I was fitted today into the GT3 (A1) Graphite Design AD IZ. What a difference!! Plus 6 mph swing speed. Plus 9 mph in ball speed. Carry distance was plus 23 yards with plus 17 yards total distance. Tried all the 'other' brands and didn't ever come close. Titleist well done!!! and thank you for taking my game to the next level. I'm proud to be a part of the Titleist Team!!
