WotLK MM or BM for PvP?

[SomeWoWnoob]

So iv really started getting into PvP lately, but still main PvE. Just do it to keep myself not bored and what not. Anyway in PvE im in MM spec and in PvP too, different builds though. But lately iv seen a lot of BM hunters in PvP and was wondering if its worth to switch my PvP MM to PvP BM spec? Is there any difference in sense of DMG and playstyle?

The BMs seem to use either Core Hound or Chimera too

MM is the standard Hunter PVP spec for this expansion. Survival and BM have their place but MM is just superior overall. More burst, more CC, more control, more defensive options, etc.
