I think all these points are perfect, especially attitude and tumbling on hard floor.
The hardest parts for a lot of allstar kids and parents to understand are, one, not everyone has a spot on a team. Unlike Allstars who don't cut, colleges cut kids, and they can cut you for any reason (attitude, skills, even appearance at some schools). Also, unlike Allstars, the overwhelming majority are thought of by their athletic departments as just spirit squad who can compete if they want to and if they're allowed to, and must fund themselves. The majority of schools have extremely small budgets for their cheerleaders and what you do when you're not as a game is not important to them. They really only care about you when you're at games. Obviously thats not true for ALL schools but the majority.
