So I'm checking out a couple of bjj gyms to start taking classes. One has a Royce Gracie black belt. The other a Pedro Sauer black belt. Didn't Pedro get his Bb from Rickson? I know they are the same animal, but do they differ? My main reasoning is I want to learn to protect myself and get in shape, plus I took some classes a long while back and fell in love. I know that it seems, and correct me if I'm wrong but some schools want you to compete to earn rankings. Maybe I'm wrong but it seemed that way at the one place I went.
