i have no known experience in jjj... as i followed (probably the most common for americans) the path of being a wrestler who got into bjj for sub grappling, then into muy thai and boxing for mma out of that. i do use a few judo throws (and a whole plethora of wrestling suplexes/drags too).
what are the fundamental differences? i've seen the old kimura videos, but where do the goals differ in jjj from bjj?
