Could you please expand on your belief that the clubshaft rotates about the COG of the clubhead?

When I swing a golf club or a hockey stick across the front of my torso, I can see the clubface closing so that the toe of the club eventually passes the heel. I can also see that the clubshaft hosel has a rounded arc motion. However, I cannot see the clubshaft rotating around the COG of the clubhead. Where should I be looking to see that phenomenon happening?

The best swing example I can think of is Ben Doyle's 'full roll'. He gets the clubface basically pointing back down at the ground through both arms straight.

As the toe is passing the heel, the shaft has to move 'out' around the sweetspot, if it didn't, you would be blocking or off plane.

Even thought Ben's finish swivel is more than most, his hinge action can still be correct, because hinge action is only in effect from impact to separation.

In the example of the stick/string - that has no offset of the clubface from the shaft, so there would be only one line of pull. A golf club has shaft droop - because the physics are trying to align the clubface/head with the line of pull, which is offset from the shaft.
