Hi, I currently have 714 AP 2 irons 3-PW) with S300 shafts. I hit balls at demo day with a 7 iron with graphite Recoil F4 110 gram shafts and really liked the feel and results. My swing speed increased to 89-90. I'm 59, and play to a 6 handicap index. I live in the Boston, MA area, and am a member of the Harmon Club. Does Titleist offer these shafts? Thank you, Jim Email; Hoop28@comcast.net
