I have been playing pool for a mighty long time, and yet I still tweak the things I think can be improved.Have you decided you have had enough of one step back for two steps forward and if so why and when. I am not talking about the mental aspects, patterns, safeties, etc.. I am curious about the physical process. When was your stroke straight enough that you were just going to accept it as is. When did PSR quit needing improvement. This pertains to the higher/highest level of players. Th Bs and below should still be working on this stuff if they want to improve or they should be playing eight hours a day, every day. We all know you can make anything work if you practice enough but for most of us this just isn't possible. So when did you forget about making the physical stuff the priority and just worry about the rest of it?
