I'm hanging indoors from 2 anchors ~15' apart with a 40D(1.6) Dream-tex single layer Eldorado, I have hung it several times and nearly every time no matter how much adjusting I do I have a ridge that runs the length of the hammock right down the center and presses against the back of my knees. I have read tons of stuff on here and tried adjusting everything I can without modifying the hammock. I've tried tightening and loosening the suspension, highering and lowering each end, shortening the ridge line by wrapping it around a carabiner one loop at a time. I am completely out of things to try... Any thoughts? Would switching to a double layer hammock alleviate this?
