Paid off oldest CC keep it open or close it?
Close the account.  The age doesn't outweigh the fact that you have to pay for the card.  It would be one thing if the credit line was a couple thousand but showing the credit bureaus that you are staying away from the $425.00 doesn't really make them think you are any more trustworthy with your available credit.  Utilization matters when you are staying away from much larger chunks of your available credit (across all cards).
