What are your cards? Balances?
To get optimal fico score you are playing the game of utilization.
Pay off all your cards except one. And keep it 1-9 percent of your total credit available.
For example.
My credit limit reporting is 8100 so I need to keep it 1-729 reported on one card.
From what ive read 7% gets you the most score for your balance. (get it bang for buck)

You can use the other CCs as much as you want during the month. Just PIF *before* the statement cuts and be sure not to use the card for a few days, so that nothing new posts between your payment and the statement cutting.
Just as an example, I missed a couple of payments before the statement cut this last month because of a hectic schedule. One CC reported a $12 balance on a $2500 CL and my FICO dropped 10 points. A second one just reported $190 bal on $3000 CL and it dropped another 6 points. As you can see, these are very small balances on decent CLs, and yet my FICO was affected by 16 points total for the 2 cards. Of course, next month, the score should bounce back after they report a zero balance again. If the balances were higher, the FICO drop would have been even greater.
Cannot agree more with you. +1+1+1+1 
Same happened to me 2 months ago. I only had 4 cards and my CapOne reported 7 dollars making it 2 cards with balances and 2 with 0 util. My score dropped 14 points.
Util was 11% I think at that time.
I'm on iPad so I wI'll try and keep thiS short. Util is calculated on reported balance. Reported balance usually happens once a month. Most common report date is around your statement date. Use your card as much as you want, but pay what you need to so payment hits just before statement date to whatever you want reported balance. Not all cards report on statement date and cards don't always just report once a month. This is where paying attention to how your cards report come in as well as research. 1-9% util of both one card and total utilization with the rest of your cards reporting 0 balance is ideal for highest fico.

I have two cards, so keeping one reporting zero balance and the other reporting a balance would be the best way to boost your FICO score?
Example 10% of my first card $2,000 = $200, and 10% of my second card is $240. Add both CLs gives me $4,400 and 10% of that is $440, the same amount if you only have a 10% balance on each card individually (isn't it better to have a balance across cards?). Where does having a zero come into play? Wouldn't the company report your zero balances which from what I read is not bad but not good either.
So far I see two schools of thought, the people who never want to carry any outstanding balances reported and they payoff and push payments before the statement cut off date. And now I see the only keep one or half of your cards with a zero balance people. 
where do you get your information? Or is this all just theory.
