I got into it with a club pro about whether or not an arched/bent left wrist opens/closes, the face of the club. I was unconvincing! I remembered this thread and vjapron's contention that at the top of the swing an arched wrist is in fact causing a shut face etc. Does anyone know for sure? I tend towards an arched lag-insured left wrist at the top I can also clear the left side of the course with the best of them! This would be good to know. Okie out.
