Combat for Pvp? (non-daggers)

I havent played much after cataclysm and was thinking of making a rogue. I have played the hell out of sub and assassination always using daggers and was wondering if its possible to pull off pvp as a rogue using swords instead.

It works, but you're performing better with 2 slow handed.

I killing evry sub rogue with my combat rogue.In Lich king i kiling sub 6,2 gs with my 5,3 combat.
