I've been told with my current gear I should be around 2100 dps
Based on what? Supposition? Or do they have a reliable mathematical model showing as much?
Grrr.... I hate that whole "you should be XYZ" nonsense when it has nothing to back it up other than guesswork. MEH!. Here's my preferred raiding Mutilate build. At least, it's the one I used for Sarth =)
Note that Turn the Tables is there over Master Poisoner because we had a very high attendance Ret Pally (their buff and the one from Shammies will knock our MP one off). If you do not have the buff from elsewhere, bring it. Also note that I experimented with Imp SnD with some success once I scored some more hit gear. But that's a bit more involved (it can be used to synch with Rupture uptime). Vigor "can" also be of some use (taking the point from Imp Poisons) when glyphed, but that involves an odd type of energy pooling that's more pain than it's worth IMO.
As the Hunter (grrr!) noted: Vulajin's spreadsheet is teh awesome. It can really help you optimize but it's not a magic eight-ball. It'll only point to potential, not guarantee results =)
Sinister Strike does not belong in any Mutilate rotation. Evis only on trash, Envenom is better on bosses of course (although this could be argued within certain criteria) due to bypassing armor. Mutilate on short trash (2 or 1), FoK on big trash (3+).
I fell into the habit with poisons of swapping from trash to boss. Of course, I did the same with gear but .... I used WP/WP on trash and DP/IP (IP on the faster weapon) for bosses. Seemed to work great compared to my experiments with different set ups.
And finally here's my mutilate "rotation" speech: There aren't any.
Think of Mutilate more in terms of priority rather than any set rotation à la Combat.
HfB > SnD > Rupture. Dropping Rupture is excusable. Dropping the others is not.
Other than that, read up, practice, run a stupid silly amount of heroics and here's to phat lootz!

Side note: Where were you Feyras??? We did an alt naxx25 and you were nowhere to be found.... L2login nub =)
