have fixed rosters at the beginning of the season with some flexibility to accept the kid who just moved to the area, and allowing players to move up,(ie..an "A" players moving up to "AA"), but not allowing players to move down during the season or for tournaments. also, have a deadline to allow clubs to move players up.

seen too many "A" teams show up to a tournament with their clubs "AA" players. kids tryout and make teams based on their abilities demonstrated, it is wrong for clubs to play kids with higher abilities take advantage of lower bracket tournaments just so they can show off the hardware on their websites!
