Interesting... a lot of these seem to reflect the different facets of Brazilian Jiujitsu. There is sport BJJ, and BJJ for mixed martial arts, and the oft-forgotten BJJ self-defense syllabus.... even the concept of Freestyle Sambo sounds very similar to no-gi BJJ; the addition of chokes mirroring the higher prevalence of leg locks in no-gi. flashlock.... I'm not meaning to call you out or attack you or anything. Given your previous strong statements regarding Brazilian Jiujitsu in comparison to other martial arts, I'd like to know how this plays out with other systems which are similar to BJJ in technical application and have similar 'track records' in open competition and military service.
