Yoda,

Thanks for the prompt and well organized reply to my post. I just want to address your item #9, for now. All three golfers you mention are, or have been, world class. To do that, they have to have a four barrel swing method. This means to me that what appears to be angled hinging is really a combination of horizontal and vertical hinging. (Is this what is Homer called "dual horizontal hinging"?)

When using the Right Shoulder to launch the Driving Right Arm, Palmer, Stadler and Trevino are Four-Barrel Hitters, not Four-Barrel Swingers.

Dual Horizontal Hinging employs a Dual Hinge arrangement: A Primary Hinge -- the Horizontal Hinge -- to control the Clubface alignment and a Secondary Hinge -- the Angled Hinge -- to keep the Clubshaft On Plane.

Angled Hinging employs only one Hinge (because the Clubshaft is already, by definition, On Plane). Hence, there is no 'Dual' Angled Hinging.
