Rogue questions

[Renzuk]

I decided not to leave my rogue at 29 and am currently leveling

I have 4 weapons to choose from

Torturing poker
Zealot blade +15 agil
The butcher lifestealing
toxic revenger lifestealing..

when i use the two daggers my damage is lower.. but i attack a lot faster.. and i prefer to use ambush as it pretty much brings the mob down halfway.. as i level though should i get a sword for the offhand? and combat is the best spec for leveling right?

[:pic:]

sword for lvling an dagger for pvp, even twinks prefer take 1hit ambush if u have good gear >.>
