*toot toot*
So obviously we're not the world's lightest according to this thread, but we built a proper ramp at 1.5-1.6 lbs. Made of lightened, corrugated display board, with just the bare minimum amount of 3/4" by 1/16" aluminum angle and plenty of 3M double stick tape, it did the job just fine. Dropped a stack on it, drove over it with the robot, grabbed it and folded it into our robot with our intake... no matter what we did to this ramp, as soon as we grabbed it off the field it sprung back to its original shape, ready for more. Never broke.
