Rogue DPS, Mutilate daggers.

Usually i just grind through the quests but i am kinda getting burnt out on that so i wanted to take my 3 rogues into an instance. BUT i dont want to be the scrub since i am all 3 dps.

i am level 69 and my dps on the dummies (non elite) are around 600 in the beginning but it usually remains constant at 450.

My rotation is multilate, slice and dice (to get the buff going) mutiliate, mutilate envenom, hunger for blood (to keep buff up) (mutilate, mutilate, envenom, hunger for blood), (), (), (), ().

Its very rewarding because the crits are unbelieveable on 5x envenoms.
YES i do use deadly poison.

But i feel like 450 on a master's training dummy is a little low.

ANY tips?

AND, do any of you know of a Addon that allows me to (real time) see what my other 2 rogues times on their buffs, energy, and combo points? Thanks again.
