I am a 72 yr old golfer who is a titleist person totally. I have posted in past about trying buying and borrowing every better brand of clubs thinking it would be better than titleist products. I play 6-pw in ap1s vokey 54sandwedge and scotty 1.5black also 913driver fairway wood and 21hybrid. All clubs are soft flex graf. Including sand wedge my question for any of you CERf fitters or any of the good people that reply on this site I hit driver 210 what if any help would the new driver out soon help me I think shafts are interchangeable.thanks harry
