Al, I thought your explanation of early wrist movement causing the club to go behind helpful. I have to watch bringing the club back behind me. I haven't paid attention to whether I might be using my wrist to accentuate that bad movement. I'll watch for that in the future. Thanks.
Excellent job Alistair in explaining difference between wrist hinge and wrist cock. In watching your video, I concluded that I have been using a wrist hinge and just recently went to a wrist cock. I found that the wrist hinge was producing too much "floppiness" in my wrists at times. Although it's still a work in progress, I feel I will benefit a great deal more with the "wrist cock!"
