Hello, I was looking for Bi-axail and uni-directional cloth as the seem to be teh best strength/weight, and found suppliers that offers TRI and QUAD axial weaves. I know the fabric would get stiffer/ less drapable with every additional layer, harder to work with on curved surface. I was wondering, has anybody used a Tri/quad axail cloth before? Thought it might be an option for something like a pickup tonneau cover? What was your experience, Pros/Cons? The weaves look pretty trick/crazy, might be a nice option on style/looks?

3600gsm is ridiculous though, that's serious stuff. Must be as stiff as a sheet of ali!
