Which spec for Leveling?

I'm thinking about rolling a rogue. What spec do you guys think is best for leveling? I know it really doesn't matter all that much because everything falls over, but is one clearly ahead of others?

Have yet to do anything more than dabble in Ass/Sub so I may be biased, but Outlaw seems to have the best toolkit for speedy leveling. Iron stomach, dirty tricks, vigor, grappling hook. That said, soothing darkness (level 60 sub talent for 3% hp/sec while stealthed) may still beat outlaw.
