The ruling spends just one word, "plywood", on the most important part, but goes into great detail and updates about trivial air gaps. It just doesn't make sense!

Al - I'll bet you a dollar to a doughnut (no Krispy Kreme please) that a 35" slab of our plywood will take that hit.
In 2007 we had a bumper of high quality plywood unsupported over about 30 inches. It snapped like a twig our first match. We replaced the wood and it happened again so we played the rest of the regional with a broken bumper. At our next regional we replaced it with cheep Lowe's plywood and it lasted almost the entire regional before it broke (it had more spring.)
