Right on ScottK !
Speaking for myself, I've got nothing against coro.

Maybe not the best material for FF planes, but certainly tough, cheap, easy to work with, etc. Used a bit of it in my life. Once, even got to spend a weekend with Tattoo at a combat meet. Majorly cool guy. Anyway, hehe, hadn't thought of that, probably hard to beat coro in a hurricane.
