The problem with the fiberglass hood breakage is not with the hood itself, but a simple design flaw overlooked by JD. After awhile, if the articulated hinges on the older models, and the plain hinge of the newer series lack lubrication,
they fail to open in unisyn. The hood then twists and breaks by the carriage bolts. Ask me how I know.
Sure, a thicker hood would help, but the hinges need to be joined to each other by a crossmember.
I made one by cutting a piece of 2 inch conduit
with a pipe cutter for an even cut. Then I pressed on a plug at each end that I cut with a hole saw to locate a 3/8" threaded rod though the center, then though a hole in each hinge to cinch them tight to each other. You could substitute trimmed washers or better still, weld the conduit to the hinges at each end. Now the hinges will ALWAYS open together.
