Thanks to Matt's Polycryo Tube Tent I've been wondering if it's strong enough to use just as a tarp? Everyone says how great they last as being used as ground sheets but I wonder how well they would hold up to wind. Of course I would not be setting it up on a ridge but anywhere where there's a wind break.
So has anyone tried this before? Also what do you think is stronger a Polycryo sheet or AMK blanket material?
