Are you guys having the same conversation?!?!>!
In boxing, the spinning back fist isn't allowed, in K-1 however it is. Back fist in general isn't favored in the boxing world, if you hit, you hit with the front of your knuckles. But I don't really care what they say, I'll hit with whatever I want to hit with, it's my body.
