That's really a moot point. From driving previous robots, I've noticed that motor stall and joystick sensitivity at low speeds is a BIG issue. Since I imagine you don't want robots climbing at high speeds, then you're going to be dealing with robots turning on your robot no matter what.

I think it a plausible sequence would be like this:
-Team is driving very slowly up skinny ramp
-Team stops to make sure orientation is good
-Team attempts to continue at low speeds, but one side un-stalls first, causing the robot to rotate. They now either have to deliberately rotate, drive off and try again, or just give up and hope they reached 4".

Which makes me realize that painted-on markings for vertical displacement of 4" and 12" on any given ramp would be a very good idea. Also, having your ramp removeable between matches would be good. Who wants a 4ft ramp above their heads if they know before their match that they'll be climbing an partner's ramp?

Keep in mind that all those holes will reduce the structural strength as well. I'm sure nobody wants to see their robot fall through a ramp...
Your ramp certainly doesn't have to be a flat piece of metal. You could probably get away with a honeycomb-like bit of metal supported by some posts, with thin carpet on top.
