well, living in the lovely location of south florida, i have a little experience with "hurricane tarps". i looked up the ones you are looking at and, in my opinion, these are aftermath tarps - for all of us with roof damage after the fact. there were a lot of them here after - francis, jean & wilma.
i am also building a monkey hut and my tarp is coming from creative shelters. it is VERY heavy, 100% light/rain proof and was recommended by the guy at galaxy hut. i was able to get a 20x24 for about $80.
just my 2cents
