In my own anecdotal experience and from various bits found here and elsewhere: for optimium scoring your number of reported balances should be less than half of your total number of revolving tradelines. The conventional wisdom of only one reporting a balance is easy for everyone to understand, thought this might be a YMMV situation like so many other things in the model.
I have 8 cards (no other revolving tradelines), and I have no change in score (Scorewatch tracking backed by DCU/Walmart monthly for testing purposes) between 1, 2, or 3 cards reporting -- looking back at historical scores and doing the napkin math based on SW tracking balance changes, I might not even have a difference with 4 cards reporting but I'm going to have to test that out maybe this next month along with 5 cards reporting just to see the difference with my own report.
ETA: Blondy it might depend on where you are on the curve - with your godlike scores, anything slightly off the top of the mountain might be a derogatory whereas in my lowland plateau my own score has a lot more tolerance built in.
ETA2: Whenever I do get to a point where I'm applying for something I really care about (read: mortgage) I'm only going to have one report, but in my general FICOwhatever existence currently I report 3ish cards consistently without worrying about it.

Sorry, I am new to this but just to clarify, you said "when the statement cuts"
Does that mean PIF between the time I receive the CC bill and the actual due date?
Yes correct you got it
