Agreed, last year 330 didn't have a single sponsor showing through the first minute and a half of every match, unless you could see in between our ramps. We passed inspection. We had team numbers in 8 places, though--one front, one back, three on each side (1 bumper, 1 outside of ramp, 1 inside of ramp)--to make sure we always had four numbers showing.

All our sponsors were on the inside of our folded-up ramps; they showed when we deployed.
