Burner thanks for your post. I don't see or feel my left wrist cock just by making a fist the way you described. But this has been a great thread for me. What I think I might need to work on to keep my right wrist level is adjusting my left hand grip: I think I might be gripping too high in the palm, need to get the shaft more under the heel to get a more free hinging action. I'm going to experiment on the range this weekend.

Woody,

I guess that is my point. You don't see or feel it because you don't realise that the wrist, in the condition I described, is "cocked".

You might also benefit, I know I did, from slackening off on your right hand grip.
Try keeping your right thumb off the club and your index finger just resting against the back of the grip rather than curled around it. You will still experience the support of PP#1 & PP#3 on the club shaft without your right hand overriding your left hand's club face control.

Shortening your back swing will also help you to guard against adding to the wrist cock as you move from the top of your swing to the end.

Cut the back swing off at the top - i.e hands at around the height of your right shoulder.
