I took what boardmember said to heart and it has worked out well for us. It was tough leaving at first but we got over it in about an hour. Her new PC doesn't speak of our may even know the term Internal Rotation, but he understands and promotes the proper way to throw a ball underhand. The place we left was greaqt in alot of ways but taught a bowling motion and would not even discuss anything else.

Other than people who have read this forum, no one else would know the term "internal rotation". It's my understanding that BM started using it to give us lay people a biomechanical reference that we could better understand the natural rotation of the arm from 12 o'clock, to and through release. It's too bad your PC was unwilling to work with you on trying to achjeve better mechanics with a slightly different approach. The problem with the "bowling" style is that you can achieve some success with it as you can see from the orginal post, but in the long run it seems limiting to the pitcher that strives for more.
