I am sure you know that clubs, shafts, grip are truly just personal likes you derive from hitting them (preferably on a launch monitor). Having said that, I am 5'10", 180lbs, 66 years old with a 13 club handicap. I recently traded my cobra S2 driver, 3w and 5w off for the new Rocketball driver, and the Taylormade 2.0 3w, 5w, and 3h. I averaged only 200-206 with the Cobra S2 driver and around 165-170 with the S2 3w. I am now averaging 230 with the RBZ driver (xcon 5 shaft) and 180-190 with the superfast 2.0 3w and all are straight as an arrow. The Taylormade 2.0 3w, 5w and 3h all have the xcon 4.8 shafts and all I can say is, I wish I had bought them a long time ago. Hit em long and straight.
