Good Shadow Priest Spec?

Ok, I know this information is "easy" to find, but what i'm running into is that there are so many freaking spec's talked about out there it's hard to make sense of which ones are actually decent.

I'm just coming back after 5 months hiatus so it's a bit overwhelming to figure everything out. Does anyone have a shadow spec priest build they love? Am I shooting myself in the foot by not going for a more healing-centered build as far as PvE or PvP goes?

Good shadow spec is the same as it was 5 months ago.

I thought there was a major priest revamp making them decent damage dealers? (Second hand information)

shadow has always been good.. they mostly changed the other trees.
Find a spec your self, or go to the wow class boards.

Is Shadow Weaving still broken? (Doesn't stack like it says)

Pretty standard PvP build.

Slight variation if you don't mind healing while grouped

Something like this for PvE dps.

No, shadow weaving isn't broken, it stacks just fine.

Does the vampiric embrace healing go on your aggro bill?
