Hunter Leveling Spec

[:1]I am leveling a brand new hunter with pretty much full heirlooms(chest, shoulder, head, cape, bow, 2 dags) and I am wondering which spec is the best for leveling. I know that in the past it has been beast mastery but I was thinking that with how ridiculously easily i kill mobs without them touching me and therefore having no need to have a pet tank mobs it might be better to go Marksman? Also since Marks is the primary pvp spec at 85 and I will mainly be doing pvp I think that may be the way to go just for being used to the spec. Would it still be better to go beast mastery?
With full BoAs, you could probably level easily in any spec.

I find SV a very good spec for solo leveling with until 51 when MM starts getting Rapid Recuperation, which gives 50 Focus per killing blow.

In low level dungeons, BM seemed clunky to me because Kill Command only works when the pet is in melee range, and pets have no speed boost so "waste"a lot of their dps running to mobs. MM may have problems getting the Aimed Shot crit bonus on mobs above 80% health because mobs die so fast.

In the 19 xp-off BG bracket, SV is the preferred spec because it offers more damage on the move than MM.

BM's weaknesses in low level PVP are the same as for dungeons mentioned above and the ease with which pets die in low level BGs. Hunter pets gain a very low percentage of hunter stamina at low levels since Cata. My 19 xp-off hunter lost over a third of pet health when the Cata changes hit.


I've had alot more luck while I was questing in BM.

MM
mobs die in one hit.
Imo, All hunter specs are viable for leveling, BM still tops the charts tho when it comes to soloing group mobs however

But to be honest, chose the spec that you are going to be at 85, Better to get used to it now in leveling so you know what to do with it at 85
