So right now my MF sorc is a meteorb, and I'm finding that even with some decent gear and all the helpful quests (Anya and such) I can hardly kill most things in hell, I'm doing about 4k fireball damage and 400 orb damage...

My question is this: I want to roll a lightning sorc if for no other reason it's more enjoyable, but it will be quite a while before I get a infinity... Could I still do most MF runs?
