JUST PURCHASED NSA2.0, WATCHED IT NUMEROUS TIMES ALREADY. ONE QUESTION THOUGH, IS IT WRONG TO INCORPORATE THE TWISTAWAY ACTION IN YOUR BACKSWING AFTER YOU COCK YOUR RIGHT WRIST, THANKS IN ADVANCE.
I was having this same problem- opening the clubface when my left wrist cocked up (about 2/3 back for me). I had to really hold the tension (aka the twist) in my left wrist and keep the clubface pointing away from me. You might want to think about Brian's image of dribbling the basketball against the wall. Your right palm will face away from you if you do this. There was a lot of tension in the left wrist at first, but now it is gone. This brought me to the top with more of a skyward looking clubface.
I really could not believe how sloppy my left wrist action had been- and then I wondered why I couldn't hit solid shots. Go figure!
