I will admit my ignorance here. Been playing golf for most of my adult life and had never been professionally fitted for a driver. Honestly, I thought we were going to try a couple heads and some different "stock" shafts and that would be that. That is not it at all. There are virtually thousands of different head and shaft combinations they can try. My fitter Jeff gave me the run down on every shaft we tried and almost what I could expect out of each combination. I was amazed at the results. Picked up 12 yards of carry and another 12 or so of roll. Shot dispersion was almost cut in half from roughly 40 yards to 25. These guys know their stuff and if you want to improve your game I highly recommend the guys at Club Champion Golf.
