Ours was built with black pipe with pvc outside it. (Not having looked at the specs carefully, nor looked at the Kickoff structure, I have no idea what it was built to.) It is bouncy, especially during Jumpball, but not too worrisome. We've got enough students that know enough to tell others not to hang from it.

I would think, Dave, that a hanging load is not very likely during a game, but in our limited experience so far I'd be more worried that a robot would push or pull the overpass sideways (such as in hybrid mode when the robot doesn't know better), or even worse one gets tangled in it while driving forward with another pushing along behind. Would the plates holding up the overpass be held down by the carpet enough to resist a wayward robot?
