Felg vs deep destruFollow

Hi guys

I have played quite som heroics with my current spec, and im quit satisfied with my dps, 2k'ish with okay group. And I feel that to get a decent gear upgrade I need to move to raids.
But in raids I wanna be the number 1 dps, and im wondering if with my current gear i should respec to some deep destruction?
I know that my hit rating aint that high, so that might be the biggest drawback from the deep destro spec?
On the other hand, with my high crit from gear, then i should be able to do alot of fire damage with all that crit?

So what do you guys think the best spec for my gear is in your opinion?

I have linked my char on armory:
