I'm expecting a new tarp in the mail soon. Switching from a Kelty Noah to a Warbonnet Mamajamba.

How high above the hammock ridge line should I hang this tarp? Is it dependent on the weather?

I'd imagine that temperature would dictate height; on hotter nights it should be higher above me and staked out further, and colder nights lower and closer. Rainy nights should be the same as cold nights, I guess. What about rainy and hot?
