i'm just starting to assemble my hammock kit. i just recived my wbb 1.1dbl last week and am starting to look at tarps. my first choice would be a cuben. money being what it is, i'm thinking for the time being i would just get by with a more modest kelly tarp.( the first few outings will be motorcycle camping so weight isn't a big factor. either a 9square or 12. with the 9(assuming my math is correct) that makes a 12 3/4' ridgline. is this big enought? or would i be better off getting a 12? this brings up another question- has anyone created doors useing an oversized tarp( without cutting it down) by just folding?
