PvE Instance/Raid BuildsFollow

Hey guys,

Been checking out SP.net and some other wowhead esk sites, trying to get a feel for the highest DPS PvE build. I have been using the standard combat swords build, and I have to say, it is getting to be a real pain. Its not doing the trick. I have heard many things about mutilate and its apparent status as "highest dps" PvE build. Experienced rogues - can y'all show me some lvl 80 Mut builds that you favor/any other high DPS PvE builds - I want to glean as much as I can from y'all's "expertise," if you will pardon the rogue pun.

Thanks guys,
Jemac
