Generally the plane you will swing on is dictated by the clubs lie angle, set the club flatly soled on the ground, your startup and backstroke will go backwards upwards and inwards simultaneously, the hands and clubhead should travel up the same line as the clubs intended lie angle to about the halfway point in the swing then it will likely shift up to a slightly steeper plane, I realize a good video is necessary to really demonstrate this I will try to put one up ASAP.

Thanks. So I presume then that if you set the C-plane at the club lie angle so that the head and shaft rest on the plane from start up to the halfway point, then it would be a mistake to try to keep the shaft on the C-plane from halfway point to End (because you are shifting to a steeper plane). That is one of the things I was not clear about, and without your reply I would have just thought that the goal is to keep the shaft on the plane for the entire backswing and downswing.

Also, in the Hogan book I recall he said that the downswing plane is flatter and points a bit right compared to the backswing plane. That is another issue that I am not clear about, as TGM doesn't say that the plane line changes as far as I am aware.
