I have a son in the Academy.......but I have good friends with very talented kids who chose CESA over Academy. They did it because they felt their kids had a better shot at going to the schools they wanted to go to via CESA, becasue of the coach involved.
So to your 3 reasons for bypassing the Academy, in fairness you need to a 4th. Which is, a parents honest perspective that it is better.
