I’m 74 and played to a 2 hdcp for years. When we retired and moved I had moved into the 3-4 hdcp range. Since then I’ve been playing TS-1’s with TT Elevate 95 R. My handicap is now up around 10. This shaft was recommended at the last local fitting I took. Most of the time I’ve had these clubs I’ve been struggling with fat shots, thin shots, and very toe heavy shots. Recently found a used set of Ping’s with TT DG stiff. Two range sessions and I haven’t hit a fat shot, thin shot or toe shot and am striking the ball well sgain. SW on the Pings are D1. TS-1s are similar.
