I have always, in my short hanging life, hung my HH as tight as I could. I'm starting to get the impression its not the way to go. How tight should the hammock be hung? One post said the ridge line should hang 45 degrees from the tree, is this all personal preference or is there a weight distribution/comfort reason for this? I've seen the graph of weight distribution, force upon tree, means nothing to me. How bout a little explanation on this. thanks
