I guess my preference would be Bayless, Weeks, Smoger....And although he was not some great ref, I always loved Cappucino. Noone could make a fighter feel ashamed like him. See Lewis/Briggs.
Smoger has bigger balls than most boxers out there. I remember him from Wolak vs. Rodriguez 1 - Wolak with his eye bigger than his head but naahhh... ,,Let them fight!". Gotta love Smoger. Everytime I see that he is the referee I know that it can get wild&nasty
