I'm voting Big Nog although my vote goes out to both of the twins.Simply put, you will NOT stop a Nogueira. You may beat them by decision, but they are never ever going to give up and they are never ever going to get knocked out. I've seen the both of them take unbelievable amounts of punishment and just keep going. Sakuraba would be next on my list.
