Posting in Sumo as it seemed to fit: opening a discussion on Chinese wrestling - shuai jiao (note sumo -chin. Xiang Pu -is an old term for shuai jiao) and Mongolian wrestling picking up from the newaza thread.
There are some interesting elements in these arts (and sumo)vis-a-vis a "delivery system" for jujutsu-like skills and in some cases a more combatives oriented approach as opposed to Judo/BJJ. Might be interesting to explore.
Cady if you think this should be posted somewhere else feel free!
