What part of the wrist?

First, stop drinking! But I'll play with ya- awhile longer.

We're using the "wrist" in Golfing Machine terms- Chapter 4.

Actually the "wrist" is composed of 8 bones and I'm not talking about any of them- since visually they are of no practical help. In regards to the concept "flat left wrist" - It's the relationship of the back of the hand to the forearm- we could break out the bone relationships but you get the idea- unless you are into the second bottle

In regards to the concept "vertical left wrist"- It's the relationship of an (open flat hand and the forearm) to the ground i.e. back of the hand and forearm against a door. Then you take the grip. After gripping the club, the back of the hand from pinky to thumb normally doesn't form a flat surface. If you were trying to determine "vertical" to the ground at that point- you'd need to use the middle of the back of the hand for the best reference.

If you haven't passed out - I'll give you one more before I start drinking.
