I have a few suggestions. Rather than post a 1,2, 3 list I'll just daBurg here for a minute.
It's natural to want to see Arab or Jamesn running the cage but I don't think either would accept it. If they would it would be worth the experiment. Bishop comes to mind but he kisses certain peoples ass. A while back it was Ryan Knox, then Kurt Lockwood and Lord knows who's ass it will be next week. The moderator of the monkey cage can't kiss anyones ass.
Willie D could handle the job if you could keep him off the liquor long enough

John Floofin could do the job, too.
But realistically, I say open negotiations with Gaupo and sign him as soon as possible.
