Bull - my old boss had done a range of martial arts and the one he found most useful borrowed a lot from eastern techniques but was essentially for real world situations. So there was a whole heap of grappling, hand to hand, kick boxing, fighting with staffs, 2 on 1 situations, 3 on 1 situations (for his black belt he had to fight 3 confirmed black belts one on one for 3 minutes each and then fight all three of them at once for three minutes). He had a week off work after it, but he reckons it was extremely useful training. If you like I can find out exactly what it was called.
