I too don't get aroused by a catfight until there is hairpulling, and even a step further, I need to have both girls pulling hair at the same time or I get bored. Add slapping to a hairpulling catfight and I love it.
My theory on the people that call for no hairpulling at a real fight aren't those of us that get aroused by the fight and are there to see blood. I could never get aroused at a spontaneous real fight at the moment, but depending on the action, it could go in the spank bank for later.
