I have the DDhammocks XL tarp. It's a great tarp. I am using it with my Papa Smurf XL Roaming Gnome. The hammock is almost 12ft long, so the tarp is great. Lots of tie off points, so the ends can be closed as doors in winter. It is fairly heavy, and they call it an XL for a reason! =-O
I don't think you'd be disappointed with it in the least.
I know not how to aid you, save in the assurance of one of mature age, and much severe experience, that you can not fail, if you resolutely determine, that you will not.
