Good list, I didn't even know about some of these and forgot others. Who are the ravens! Is that the old "flying high raven Allstars?" I didn't know they were around here. Our original gym missed your list but they're really not worth adding to it. They're 5 minutes from my house, we drive 30 if that tells you anything.
I'd add Carolina Spirit and Cheer Corps Allstars to this one, they're both in the Concord Albemarle area I believe and field some fierce teams.
The other thing I'll say is I don't really think we are rivals with any of these...or anyone actually. There are teams here we get to see a lot and ones I look forward to seeing because we have friends and former athletes on them and we can catch up at competitions. There's some I look forward to competing against because win or lose you know they're worthy competition. I'm really looking forward to my kids meeting yours and Carolina spirits J4 on the mat and I am looking forward to seeing CeA Charlottes teams in the mix. All this talent just forces everyone to raise their game and I'm all about that!
Didn't really realize it until i read your list but we have some good gyms in this area!
