I play on high school golf team and have been golfing for around five years. I haven't taken a real lesson, but my average score is around 80. Most of the people I play with haven't even realized that I use a ten finger grip. I don't feel like it affects my wrist rotation or club head lag. I have hit around 200 balls with overlapping with no improvement to my game. Overlapping and interlocking just hurt and keep my from making good contact because I focus on my grip. What I want to know are 1. Do you have any tips for comfortably changing grips? 2. How much do you think my grip is keeping me from reaching my potential? 3. How much do you think it lowers my credibility? For example would you trust a teaching pro who uses a ten-finger grip?
