He's really not that tall and I don't think he will have the leverage advantage at 86kg. 79 kg he will most likely dominate, but he is too old and small for 86 kg. But, if anybody could do it, it's Kyle Dake.
I'm not sure about the rule, but criteria is the way to go. There's never a tie. Someone is always winning or losing. The ridiculous folkstyle OT to rideouts scoring is terrible.
