Rob Weizer has been my swing coach for several years now so it was easy to go to him for upgrades. New shaft in my driver picked up 20+ yds and straightened me out. We got rid of my steel shafts in my irons when I hit 70 with carbon fiber; picked up 15 yds with most of my irons. Just replaced my short game PXG gen 1's with gen 3's. He also tweeked my putter and putting has improved. I couldn't be happier.
