Re: What you are stating makes sense. The bigger shoulder turn works better with woo
Tommy Armour always said "You must not rush the start of the downswing for these forces to be applied".
Great Question! This changed by golf life forever!
I learned from tapes and books from Bobby Jones, H. Haney, and others that irons and fairway woods must be struck on a descending blow, BUT the driver should bottom out on a somewhat flatter plane (longest club) with ball across from the front heel, and strike on an upward path (thereby combining a high launch angle with LOW spin).
I read it explained it this way. When you strike down on the ball with the driver you will hit low shots with more spin (thereby decreasing distance). If you add loft to your driver, you add even more spin. It explained that "The optimal backspin for Driver is between 2,200-2,800 RPM, launch angle between 11-14 degrees, and Smash Factor 1.3-1.5 (ball speed/club-head speed)." I found the best way for me to achieve this was indeed with the flatter upward driver strike.
Hope this helps!
