Yoda - you wrote-: "At the same time, Centrifugal Force has a Line of Pull. That invisible line is from the #3 Pressure Point (first joint of the right forefinger) to the Sweetspot. This is what is driving the Club, not the Clubshaft."

Could you please expand on your argument?

I already did. Immediately after posting, I added the following text (in red) to my post:

"At the same time, Centrifugal Force has a Line of Pull. That invisible line is from the #3 Pressure Point (first joint of the right forefinger) to the Sweetspot. This Lag Pressure Point Pressure (1-L #7) is what is driving the Club, not the Clubshaft."

You could not have known this as you were responding, and I have so notified you by Private Message. Therefore, as I've advised, please take the added text into consideration and amend/edit your post as you see fit. Thank you.
