Arena partner for Enhan Shaman

Hey guys, I'm a Spriest playing 2v2 arenas with my friend, an Enhancement Shaman, but I feel that I'm not the best partner for him (And I'm not having fun playing a Spriest), i have read that Sub rogues, or maybe Ret pallys or Frost Mages are good partners, could you guys please give me advice about which class should I pick. (Sorry if my English sucks, it is not my native language)

Bm hunter/enha
Ret/enha
Rogue/enha
Shadow/enha

Bm/Enha is probably most famous comp because it's completely ******ed versus some teams, also Bm hunter is fairly easy to play. If you like short bursty games, i'd recommend Bm, if you preffer double dps comps with great survivabillity you should try Ret.
