I'm on Oahu and have been training BJJ for a while, but all the standup I've been doing is backyard stuff, mostly because I live in the sticks (Makaha). I'm moving back to town soon, and was wondering what standup school you guys recommend? I hear Master Kam's and Bulls' Pen are good, but I've never been to either. I'm looking for a place to go to 1-2 times weekly get my standup decent (I know that's not often, but I train BJJ/Vale Tudo stuff 4-6 times weekly and need to squeeze this in). Any suggestions or personal experiences?
