A new school is M-Theory headed by Ishmael Bentley (formerly @ The Academy). It isn't showing up on google maps yet 5700 W.36 St, Minneapolis (St. Louis Park). Nice school, I just joined. It's very close to Gracie Barra.
I'd second on WC's fundamentals, legit. They do very well in competition, especially sub-only. They do have two belts systems, Shinbudo MMA & Rickson Jiu-Jitsu (which is graded very old school, no quick belts).
