I'm looking for opinions concerning the structural strength of different thickness of strips...ie...3/16 versus 1/4 versus 5/16. I am not disregarding weight here, but I really don't see a big weight penalty using thicker strips. It certainly is easier to build with thinner strips. In the same grain what is the opinion of using multiple layers of epoxy/fiberglass for strength versus thicker strips. I would think there is a greater weight penalty using multiple layers of epoxy/fiberglass versus thicker strips. Possibly there is a happy compromise. At this point I'm more concerned with structural strength. I'll consider aspects of durability, toughness, puncture and scratch resistance later....UNLESS...it all turns out to be a melded combination. Just kicking a few things around. I figured some people would have their own opinions based on experience.
