Always enjoyed the match between Helio and Kimura. Even though Kimura won and had almost mythical status, the fact of the huge size difference as well as the fact that Helio refused to tap after having his arm broken always made me respect his pure toughness. I remember reading once where Kimura said if the fight lasted more than three minutes, he would consider it a loss. Kind of arrogant I guess, but so is bringing a coffin to ring for Kimura like the Gracies did.
