Yes, your forearm is going to always supinate as you come through. The amount of pronation vs supination BEFORE that happens (transition from backswing to forward swing) is what I'm referring to.
As for Borami, what you said is true but not what I was getting at. Try comparing SW Roddick technique vs SW Federer technique. They would be very different. (See Roddick vs Nadal, both using SW)
