You will take a small point hit when no cards report a balance, and in your case very small hit.
Some other CRAs may have a lesser or larger hit.
Since your score mentioned (if true fico) is in awesome territory, those few lost points are pointless 
If needed, just let a small balance report during statement cut (preferred 8% of limit or less)
and pay off in full before due date each month.
You can shuffle your reported balance to the various cards to allow use each month, if you have multiple.
Played the AZEO game for the heck of it and took a 25 point hit (reduction) due to no balances reporting. Comments were: "not utilizing credit" ... took me a couple of months to get the points back.
In our challenging times, I will not experiment any more as I don't want lenders thinking my profile is on the slide ... scary
