Proper Wrist Action: Flat Or Cupped?

A common misunderstanding among many golfers is the idea that they must achieve a flat lead wrist at the top of their backswing. Unfortunately, this is often misdiagnosed. Sure, there are players who have a relatively flat wrist at the top, but the majority of players whose photos you see actually have a slight cup in their wrist. However, due to the camera angle from which most still-frame pictures are taken, you will detect a wrist that only appears to be flat. So how much wrist cup, if any, should you have? The answer depends completely on how you place your hands and fingers on the club.
