I like having visual images of great swings that help me remember what I'm doing (BTW thanks for Yoda's swing videos =D> ). I keep watching Weir's waggle and think, "Look, Look, LOOK". See the hands, the forearm position. Back, up and in. Doesn't it look like the TGM waggle from the book? I'm thinking of incorporating that into my routine (especially I have the nasty habit of whipping the club inside on the backswing)
The other visual I'm thinking of incorporating is keeping my right foot and my head back until my hands are well past them. Good idea or bad?
