Wrath of the Lich King Rogue build

Here's what I'm thinking of for my rogue on WoW: http://talent.mmo-champion.com/?rogue=00500500300000000000000000000053230053501005201033310515020000000000000000000000000 It's a raiding build as that's what I'd like to focus on in this expansion. I'm also hoping that my guild will focus on raiding as well. I struggle for a while on whether or not to get Relentless Strikes or the Close Quarter Combat talent. I think in the long run this will probably work out better, that way I know I won't hit energy starvation (which was the main thing I wanted to avoid). If someone has a better idea for a deep assassination build I'm all for hearing it.
