Nah, I could very well be very wrong, but my head says that if you're trying to accentuate the square-ness of it all, banding lines would definitely bring that to attention.
I suppose gridlines is a more appropriate word than banding lines, but hey, I've never seemed like I knew what the hell I was saying before, why start now
