Steve ...
Are you working with Randy Kapano at Mt SAC? I thought I remembered that he was doing some kind of coaching there. (When AJ was at that more "trainable" age, he worked with Randy in his facility ... not a full fledged batting cage set up by any means like yours.)
Hope all is well.

PS Did you notice the "plug" I gave you earlier in this thread.
(You're quite welcome)
