The finger problem is definitely a result of RSI by the sound of it. I suffered from the same thing awhile back, I fixed it by reverting to bras d'honneurFfs. My burgeoning golf career is under serious threat. Been told I have a high probability of needing a total joint replacement in my middle left finger (no doubt from over use on the roads and at the football), plus the possibility of both knees needing replacement as well.
If I can get back out there at all, do they have a Tour for old robots ????
Geez. Bit devo at the moment….seems the finger alone might be a big problem where gripping the club properly is concerned.
