To me, it's simply a budget issue. Cuben is the way to go if you can afford it. I had the Tadpole and it was a great tarp. However, after a cold, windy, rainy night that I got almost no sleep, I upgraded to the HG Cuben w/doors. But I had to squirrel away some extra funds to pay for it because it certainly isn't cheap. I really can't imagine a better system. It weighs almost nothing and and gives me 100% protection. The only down side is that cuben isn't quite as tough as silnylon.

If it fits in your budget, go with the Cuben tarp with doors. Eventually, if you stick with hanging, you'll end up with one down the line anyway
