Maybe this discussion should be on an other part of the forum? Maybe in Swing instructions or practice. Sorry for that.
Just a quick reply to GONavy:-)
Maybe One Plane Swing and Two Plane Swing can be considered as a mental exercise? Something to think about so that you get more aware of your own swing? By looking for difference and comparing different styles you can distinguish different elements form your own swing?
The only danger might be that if we start to consciously control our swing, it changes. (Conscious and unconscious controls are different.)
