From my experience with the older guy, The grass isn't always greener in the other leagues rink and the devil (as in coach/team/families/kids/org) you know is better than the devil you dont.
I had to rebuild a bridge for my older guy because he went to a team that was not a healthy environment from top to bottom and from parents to kids.
Envy is an evil thing, you dont see it, feel it, but can sense it! So whatever you do, never burn a bridge cause you might want to come back. And good coaches won't burn em either.
