Scott,
Here's a link for plywood design spec's, which should give you all the info you could want for comparison. I had the Comparison stuff saved on my old PC, until it died
Best of my memory was that tensile, shear, modulus, and fastener holding strength the Coosa 20 either very closely meets or in many cases exceeds that of ply's., and the blue-26 was better in ALL catagories... But don't quote or hold me to that
