miles? I already have two cards that I'm trying to pay down. I love to travel, a free flight every year would be cool though. Decisions, decisions.

The interest on that tends to be reasonable, the annual fee can be a little high, if you can transfer your two credit card balances to it and if the miles don't expire it's not too bad, then just do away with one if not both of your other credit cards, don't risk over-extending yourself and ending with more debt than you can use.
