In this demo he used FOUR 6-foot and FOUR 3-foot pieces of cordage. And EIGHT stakes. Each setup used everything.
I can't go with less than a 9x12 absolutely waterproof silly long tarp.. -- a comment on the videoI'm of the opinion that when you hike then you JUST need the shelter to sleep. So there is no real need for all that extra space. If, on the other hand, you're camping then you might want to stay out of the weather for longer periods. Frankly I can make an argument for two 5x9 tarps (one tarp, one poncho-tarp) instead of one large 9x12.
