Very good answer.
I switched to Aero500's last year. The drop in weight from my 200's is about TWO full ounces, and the SW by about 15 points.
I hold both very loosely except for hard, deep incoming balls, which I grip harder and shorten my swing.
5'11" and 150 lbs., 4 5/8 with an overgrip. Never twists unless the player I'm facing is a 5.5, at which point, I have no business hitting with him.
