Yeah, but you know they all have technical analogues in the aiki paradigm. I already pointed out sprawl = mae ukemi and kaiten nage = 3/4 nelson. It helps if you learn how to grapple to see the technical similarities, so me just saying it won't really do anything for you unless you go try it out (friendly-like!) with grapplers.
They don't usually bite and can provide very good reality checks.
Keith, I gotta get that Eddie Bravo book. He's made some interesting (hopefully not all chemically altered
) points about combining aspects of no-gi BJJ and Greco-Roman wrestling.
