When you mentioned your scores in the first post , I must admit I was surprised, but if it works for you then why mess with it? My best score is 81 but I only play about 10 times a year . Note that only 26% of all golfers in the world break 90 so we aren't doing too badly
Because it doesn’t always work, and he has the potential to be an even better player if he gets the root issue fixed?
