Hi Peter, please allow me to address some of your points.

There's one problem with your assessment. Moe Norman does not swing on Hogan's plane. The path of the clubhead defines the plane. You cannot say Moe's clubface is not in a certain position in relation to one plane when he's swinging on another plane. To have a valid argument you need to make reference to the plane of the clubhead that Moe is using. I haven't seen the pictures in question so I can't comment on the position of the clubface.

I don't know about Arista but I agree with ctunflog. From hip high to hip high the clubface is at right angles to the plane, in both Moe Norman's and the conventional swing. Beyond that they both rotate to on plane.

> Dr. Mann has one interpretation of the swing.

Dr. Mann has the most accurate interpretation of the golf swing to date. His data is the result of 15+ years of research collected from the actual swings of the top touring pros. Their swings have been computer and biomechanically analyzed, a first for golf.

The others were not Phd's in Biomechanics nor did they computerize swings of the pro's. There assessment were based on still pictures, video and theory.

So have I and it's the best lesson I ever had in my life.

His model is the conventional swing, it was not meant to be interpreted for single axis. If you use single axis why did you go get analyzed by a conventional swing model?

I have a photo sequence of Tiger and he's exactly in the position per fig. 6-20. In fact Tiger almost matches the model perfectly in all aspects, perhaps that's why he's so good.
