Here's my design for my late spring to early fall tarp (9 ozs.), decided to go with an asym catanary cut design. Anything else would have only duplicated my superfly (1-lb-14 ozs), only without doors and a bit lighter. The size of the tarp may be a bit better than a Hennesy, because they were all too narrow in my opinion from rain that could blown in with heavy winds, this one should provide ample coverage. I also like it because it only requires 2- tent stakes rather than the 10 stakes I'm currently using. Which will in an indirect way will also take off a few extra ounces.
