Yeah there's team ROC, but as mentioned earlier their stand up is poor, though not sucking, they've got some good strikers. If you're a big guy that's where you may want to go. There is also Redpoint which has horrible striking. I've watched their fighters do an entire hour's session with their hands even with the chest. There is also Angel's Gym, which is actually where I train-though not right now due to time constraints and job. Honestly IMO the best 'fighting' gym around. Not as expensive as the others I think, but about $125/month last I heard. They train boxing, kickboxing, muay thai, and submission wrestling with BJJ. The boxing and thai trainers are awesome, reigning champs in their field. It's a small place though, but they've got a ring and a small cage. If you're in the fayetteville/bragg area I'd seriously recomend checking them out.
A side not in ROC. The ROC in the fayetteville area has a reputation for catering to the military and kinda shrugging off the civilians. If you're a civilian I'm told you're just a sparring partner for over pumped meat heads and you won't get much instruction...or so I'm told, I've not verified this. Our heavyweight MMA guy goes to ROC for sparring because Angel's has no one in his weight and Redpoint can't fight.
Oh yeah, Angel's doesn't require any fancy uniform or gi. Just show up in some fight gear, I'd recomend you bring your own gloves... the supplied ones are just worn out.
