3v3 matrixFollow

I have a 3v3 team currently that has my best me and my best friend and another of our guildies.

Me and my best friend are both rogues, the guildy is a PVE specced mage.

Our guildy really doesn't care about PVPing at all, so we're looking to replace him with somebody.

I am currently combat swords specced and just picked up the S1 MH this morning to go with the OH I got last week.

What class/spec combo would be the best to add to our team for maximum effectiveness.

I currently have no PVP gear other than the weapons, and my friend has a little bit, but I'm not too sure what. My armory is in my sig, his char is Dreadwick on the Illidan server.
