Fireball sorc pvp

Well i made a fireball sorc, just to mf though. One day i got into a dueling game and starting owning... But i was just using partial mf gear. Anyone know what kind of good pvp gear for a sorc would be? Maybe against some necro or whathave you. And all the charms i had on at the time were an anni, and a fire gc charm. Can someone tell me some good charms? I know i can't go wrong with 20vita charms, but lets get a little bit more fun.
