My vote goes out to Big Nog. Let's face it, it doesn't matter who you and what the rules are, you're not going to stop either of the Nogs. They just don't die, and that's heart.
As for who has the most balls: Probably Cabbage, because it takes a crazy mother f*cker to stand up and trade with anybody you step in the ring with, even when you are clearly the worst striker.
