I've been working on supinating my left wrist to help avoid breaking down at impact. I've been using a Tac Tic as feedback to insure that the left wrist remains flat. The problem is that my effort to supinate is leading to a severely closed clubface at impact. I'm following Hogan's suggestion of turning the left palm up at impact per his instructions in Five Lessons.
So while I'm getting improved lag and compressing the ball well at impact, the shot pattern reveals a ball flight that is initially straight, but hooks significantly at the end of the shot. Any advice?
