I actually have to say that I'm in the minority on this one.
Ex-Trinity parent/athlete has every right to prefer a particular style program. We're FAMEous, so I get the whole "flash, show, bling, fierce" thing. The fact that the family is ex-Trinity is (hopefully) irrelevant to the discussion. Now, if you want to be a conspiracy theorist, poster could still be a Trinity parent (or someone posing as Trinity parent) who's trying to find out which other nearby programs will have a J5 this season, whether or not it's been publicly announced. Furthermore, I would stick up for my program while we were members and not have the least problem leaving, if that's what my family decided to do. I don't see that as a problem at all.
My advice would be the same as previously listed - look up gyms in your area and find out where your athlete can try out (pretty sure your cp would know what style program she "likes," since she apparently knows what she doesn't like.) But have an open mind and heart - just because Susie was J5 at Trinity, doesn't mean she would make a J5 elsewhere. Don't pick a gym because of a team.
