Sub mobility talent (pvp)

[TomGreen]

Which talent do sub rogues use in pvp? I am used to running with burst of speed but i feel its not that good with sub. I have tried cloak and dagger but it felt weird not having burst of speed then. Mobility got shot down pretty hard. Then i tried shadowstep. Its actually not bad but during its cd i feel i have no uptime when getting kited and have to blow something like vanish to try and get close. So now im back to burst of speed and perhaps it really is the best talent of the tier?

arena - shadowstep, because of blind - vanish - shadowstep - sap and similar trick's
bg's/solo - BoS

Burst of speed is in my opinion too predictable. Shadowstep is quick and clean and hence my pref.
