Neil - i know you are very knowledgable about the swing but the golf history books are filled with Two Plane Swing golfers who were amazing strikers and as you put it - re-routed the club - Nicklaus, Watson, Trevino, Woods (old swing when he actually hit fairways) and on and on.

Having read Hardy's (dull) book I think the definition of one plane and two plane is that in One Plane Swing the arms and shoulders are in the same plane (roughly) and in the Two Plane Swing the arms are higher than the shoulder plane. So to me Rich looks like he is nearer to One Plane Swing than Two Plane Swing (hence he swings a touch flat).

Personally i think this One Plane Swing and Two Plane Swing thing is a little over rated. You can be either depending on how you set up at address (of course you are likely to be better at one than the other!)
