So you're supposed to start biting the instant anyone attempts any ground manipulation? Interesting. One guy I met who learned SC also mentioned he bit someone when the guy tried to do ground fighting on him but I didn't realize at the time it was intentionally trained. Is biting allowed while standing?
Uh, I don't see why it would be hard to use a specific ruleset. Just agree to use either judo or SC rules before a competition and stick w/ it. It's not like it's shameful for an SC guy to lose to a judo guy under judo rules or for a judo guy to lose to an SC guy under SC rules. Otherwise, just don't compete if face matters that much. Why make enemies of the guy who you might need to cover your back in a situation?
