ive been in a fight with a guy who did judo unbeknownst to me. i did a little bit and i grabbed him and tried to throw him which usually works against untrained people, but he gripped me properly in return and immediately tried to throw me off balance, and just the way he went about it made me realize im better off striking than grappling so i broke his grip. he didnt know much about that, thankfully. it was a 1 in a million chance but it could happen, so unless youre very confident that your judo level is high enough for a random, i think getting ippond on the pavement will suck.
