WTB: Spinnaker / Silnylon

[Coldspring]

I need to build a tarp.

I just thought I would put a feeler out there and see if anyone is sitting on a pile of waterproof spinnaker, or some regular old 1.1 silnylon?

I'll tell you what... if anyone was sitting on it, they weren't on it for long. That stuff is crazy slippery.

I stood on mine trying to do some moving around... and almost felt on my butt.
