I've searched and read the threads on others multicam tarp exploits. I've noticed that they stuck with the 1.9 PU ripstop for making the tarps. I was looking at the Duro site and was wondering if this fabric would be suitable for a tarp. I don't know much about NanoSphere except that it's supposed to be waterproof/breathable and Feathered Friends has it as an upgrade fabric. It's listed as 1.55oz/yd^2, so it should be a lighter than the PU coated fabric, and maybe close to silnylon weights. It's obviously not cheap at $11.34/linear yd with a 5yd minimum. As always, all thought, ideas, or suggestions are welcome. Here is a link to the fabric.
