I've noticed that people are selling Cuben Fiber tarps, stuff sacks, packs and plenty of do it yourself gear. However, I'm surprised that no one (to my knowledge) has started using Cuben Fiber for single or double wall tents. Is this just a matter of time, or is there some other reason for this? I would think you could save a lot of weight just by replacing the rain fly/roof (you could leave the floor as silnylon as it is much more likely to tear). I know this stuff is expensive, but I think people would pay for the weight savings (just as they pay for down instead of synthetic).
