PvE Fun Rogue Spec

Hey guys,
So I joined retail vanilla only a short time before TBC came out so I never got to experience vanilla raiding as a rogue.
I'm just wondering, what's the most fun/active raiding spec in the current vanilla right now? I know daggers seems to be a literal 2 button rotation, but I'm looking for something more complex that's still viable damage. I remember from my early TBC raiding that Assassination had rogues watching a 3 or 4 different buff/debuffs throughout a fight, strategically popping vanish/cooldowns for extra bursts, etc.
I'm still far far from raiding right now, but I'm just curious if there's any builds out there that make rogues actually fun to raid with right now or if I should just level something else and wait on my rogue till TBC is launched (next year-ish?).
