1. I don't move my head, unless it is a very slight movement. I almost always track with my eyes. If my head is moving it usually means I am doing something wrong somewhere, or a simple case of anal-cranial inversion on my part (not true of everyone, but for me it is).

2. Most every batter is a different height. Why not make it easy and lock at the top of each batter's strike zone.

3. I'm damned consistent...a heckuva lot more than the baseball umpire I helped evaluate last night who was using GD (and not using it well).

4. I think the GD don right is an excellent baseball mechanic. But, IMHO, it is not right for fastpitch.
