I can use the Photo in post #1 and draw the important Force Vectors if that's what you mean.

The Horizontal Hinge, whenever we use the term "Horizontal Hinge" we're always referring to the "Dual Horizontal".

Concerning the Shaft in Post #1, I'm almost sure that the shaft wasn't pre-stressed but neither was it whipped ahead of the hands with a backward bent shaft we so often see. The Clubhead appears to be very stable through Impact although if you look carefully at the Top and Bottom of the Clubhead and the Face Grooves, they appear Level to the Ground. So I suspect some Clubhead Droop.
