Talent build

I got a question... very many hunters r MM down to silencing shot... in the raids i think the hybrid MM/surv is better becuse on a crit u get 40% of the mana cost of the shot back and u get expose weeknes.. so if u set talents up to Thrill the hunt and expose weekness and in MM up to Mortal Shots it shud be better in raids raight?.. becuse shatter shot and silencing shot is not very usfull in the raids. Someone have tryed this talant build?

i tryed it and there isent much difrence realy, your dps is a lot lower thought and only +3% crit
and in MM you get a lot more AP wich increases you bonus damage on all your shots, serpent sting, steady shot and so on
and the mana isent much difrent, you got more MM as marksman and you can always FD - drink
aswell trueshot aura is constant and applys only a little less AP wher expose weakness is a "chance on hit"
