Just thinking.
Do you[your son] have a good partner where you are at?
To me it is what is best for your son.If he has no one in the group he is in now,that is better or equal to him.I would look for better boy to be his partner.

This year my boy of 2nd year is way way better.He has boys that killed him at the 1st of the yaer.They can still beat him now.But O my there is a ton of difrance in he moves.Coaches do make some difrance,but the boy he partners up with will make him way way better.
