Doesn't it give you more options as well, though? The one i'm using there is like 3x2m and it was just enough (helps that i'm a manlet desu) but if it was a bit larger i could've had it cover just a bit more in case it rained more than just the light drizzle we had on the first night, that being said i could also achieve that by just making the whole thing a bit lower.
alternatively could also use part of the tarp to put over the ground so you can put your stuff on top of that and avoid it getting wet or humid, or dirt or bugs getting to it. though this is pretty low priority and could probably be achieved through other means.
Anyways the rope used as support works great as a place to hang shit from so i'll probably be using similar setups whenever i can.
