3v3 SpecFollow

Hi there i hope some of you more expert rogues will take a look at this.

My rogue is almost 70. Im 68.5 now and im wondering what spec would be good for me. I will be doing pvp only on my rogue and my group will consist of 2 disc priest and me (nobody wanted 2 play a mage). We arent sure if this group setup will be that good, but we are gone give it a try and else switch one of the chars with one of the others we have. Our way of combat should be something like me stunning/dpsing one of the dps classes of the other group (pref melee) and the disc priests mana burning any mana users that are pressent. Healing shouldnt be a problem and we can dispel most crap except poisons and curses. Im just wondering how 2 spec i was thinking of going mace spec cos that target im on will be cced more cos of the stuns which will buy the priest more time for mana burning as our setup is more of a durability fight, or going sword spec for the improved damage so their healer has a harder time healing and running away from my mana burners. Maybe even a backstab spec? I dont know the rogue class that good its the last with the hunter class i havent got on 70 yet. (Only started binding all my abilitys at 61 when i started reading about rogues, damn that makes things easier still my brain/finger doesnt find the right key 100% of the time).

Hoping for some good pointers/tips, or some links i could check out.
