I'm older than most of you so my clubs are very different, but I am still carrying a handicap less than 5 at the age of 59 and did card a 66 and a 68 two weeks ago. All my shafts are regular graphite shafts, on the verge of becoming the senior version when I replace them.
Driver - Callaway FTIMix 11 degree
3 Wood - Cleveland HiBore XLS 15 degree
5 Wood - Cleveland HiBore XLS 19 degree
4 - PW, GW, SW - Callaway red backed big bertha (2008 version)
LW - Callaway 58 degree Jaws series (severe ball killer, peels them)
Putter - Odyssey red version, partial mallet
Balls are generally Callawy HX or Titliest NXT
My grips are the Winn Lite, midsize with 2 extra wraps of tape on the irons and the Winn ultralite midsize with 4 extra wraps on the woods.
