I'm living in LA and wanted to try out Jiu-Jitsu, I did some searches on the internet and found two places near me. I need your advice on which to go to. There is "Rickson Gracie Jiu-Jitsu Center" http://rickson.com/classes/classes.htm and the other option is this place http://streetsportsbjj.com/. What do you think, I'm leaning towards the rickson gracie one simply because of the "Gracie" part. I have no idea how to judge whether a grappling gym is a McDojo or not, so please help me out.
