Out of the given choices, it's a tear for me between the Primetime Players and Team Rhodes Scholars. I like PTP and I think they're fun as hell to watch. I picked Rhodes Scholars because I want to see Damien Sandow in a feud involving a title of some sort and if sticking him in a random tag team is the only way then so be it.
Otherwise, I would love to see the Usos win the titles. They are by far the most underrated tag team currently and that's just not right considering they are just awesome in every aspect. Also, if the Ascension gets to the main roster and wins the titles, that would make my day.
