I get it now.
You see things from a different perspective, but the same thing!
You see the glass as half full. Other's see it as half empty.
You say we are weaklings and pronate to achieve rackethead speed. We say we pronate to get rackethead speed thru pronation, but don't dwell on our weakness.
We both agree we cannot swing fast with an open face, so a closed face is necessary to get up to speed, then the opening to contact the ball square for a flat serve. That supports my argument that we should swing faster on spin second serves than we do for flat first serves because WE CAN!
So we are different (our theories), but the same (in actual practice)!
