Hi poolshark444,
Welcome to the forums. Nice FICO score!
What you are doing is working great for you - IMO, it's perfect for your situation.
Some folks run into high utilization reporting unless they are careful to pay down accounts - some to a zero balance - before the account reports to the CRA's (usually but not always the statement date). WIth a 799 FICO score, you're not being damaged by this. If you ever find a concern with what utilization is reporting, then adjust your payment schedule accordingly - paying down before the balance is reported to the CRA's.
But no need in complicating your life! And, btw, anything over a 760 FICO is considered primo!

Probably exactly what you are saying - just wanted to clarify.

Oh I see. That's what I thought before I came here, but I read somewhere that leaving a card(s) in your sock drawer doesn't necessarily show CRA that you are managing your credit, just that you aren't using it, or even "hiding" it so you don't abuse it. I've got 4 cards, 1 of which is my everyday use card (AMEX Clear), and I was going to start trying to get the other 3 to report a small balance every month. But if keeping zero is just as good, it's definitely much easier than trying to time the payment dates

You don't have to report a balance for the OC (and FICO) to see usage on the card. That's why lots of folks put an ongoing bill on cards to maintain usage, even if they PIF and report no balance (a good practice!)
Remember that FICO does care how many of your cards report a balance. If 100% of your cards report balances, most folks see a FICO hit. The general mantra for best FICO scores is to have less than half of your accounts report a balance. Letting one account report a small balance seems to work for most folks, and you can experiment to see if you can do as well with an additional one or two cards reporting a small balance - it's definitely a YMMV thing.
