New group, tank healer dps or tank and 2 dps?

[bryce]

I'm looking for a new group combo to raf with. I have a friend who is also dual boxing, but I'll be 3 boxing so we have the whole group for randoms. I'll be doing a tank for sure, but I'm not sure what other two classes to do. If he does a healer, then I'll do 2 dps, but I only have a limited set of boas so I can't decided what to pick to spread the boas across them.

I've got a set of plate dps boas, plate tank boas, cloth boas, mail agility boas, leather agi boas and leather intel boas.

pally tank, hunter, and a caster dps. that way your buddy is doing the healing, and your tanking with 2 ranged dps.
