as suggested above, i'd go Bear + Ret, and lead with the Bear.
the two most versatile classes in the game, you could pretty much go with any spec. But bear/ret will probably offer you the fastest/easiest combo.
Some might argue to go as cat, but personaly i can't be ask to stealth or go behind mobs when mb'ing, so a full-face bear charge and ret whirling is how i'd do it.
