Good post and I agree that Kai's personality is definitely off colored. Listening to his radio interviews is always an awkward and WTF experience. I have to wonder if he's not on LSD during the interviews. Physique wise, I think he looks amazing, relative to the pro stage. He's massive, he's detailed and he has one of the few routines that don't put you to sleep.
I'm surprised Cutler isnt' getting more attention. He looked amazing at the last Olympia.
I don't know where to place these guy to be honest, but I certainly see Phil, Cutler, Kai, Warren and Dexter in the mix. Wolf is a bit inconsistent, so I don't ever bank of him.
