I RAF'd 5 rogues to lvl 60 several months ago and decided to pick them back up and get them to northrend. I'm trying to decide what best talent tree I should go with. I never played rogues before this and am not that good with them yet.

When I logged them on I found I had to pick talents again. I guess a patched added some new abilities. I went with combat for "Killing Spree" but haven't been able to use that ability yet. Just got them setup again last night.

If there is anyone that is familiar with rogues I would appreciate some advice. What spec would you go with if you were multiboxing with them and why?
