The $59 fee for my biz and personal card (and my wife's personal card) have been posted. I have just a couple dollars in rewards left, and really no need for a CapOne card. That said, I'm not hostile to converting one (and maybe all) of these cards to fee-free cards at 1.25% reward -- but I'm not terribly excited by it, either.
Is there any reliable info as to which is better for your credit score: cancelling an unused card, or just letting it linger, probably unused?
