If the ridgeline is loose or as you say, collapsing , it sounds like you either have trees that are to close, or your tree straps are to high on the trees. The 83% rule is for when the hammock is loaded. If you are getting in, and the ridge is loose, then you have less than the 83%. If the hammock is comfortable, and your fine with the lay, then just shorten the ridge so you can achieve this lay every time. BTW, the 83% is just a starting point. Some find it perfect, others like it longer, and some shorter. Hope this helps.......RR
