World of Warcraft- Pally hunter, pally pally, or hunter hunter?

Soooo my best friend and I..are joining a new realm..just because were trying something out.and we are thinking about going those two cles. We dont know what to do reallly..if we go hunter hunter we will have the advantage to have fast leveling with the pets, which will equal to overpowering every quest. specially with two hunters. if we go pally pally we will have instant ques because pallys can fill in every role. but maybe we would get bored if we were both the pallys. And pally hunter, simply we wouldnt be able to figure out who would role hunter or pally. Any advice really?
