I once read about how Rorion challenged Benny "The Jet" Urquidez to a fight. Benny said he would fight if the following rules were put in place, whenever they got into a clinch the referee would pull them apart and whenever Benny grabbed on to the ropes the referee would pull them apart. Rorion said no, that he wasn't a kickboxer so he wouldn't fight under those rules. So it sounds to me like Rorion would fight somebody if the rules favored his style but he wouldn't fight somebody if the rules favored their style.
