Ok, so I've been looking through the archives and learning a lot, but how/where do I attach my ridgeline if I'm using para cord & knots? Does it just attach to both ends of my hammock line? I saw somewhere that most people liek them set at about 100" or so. Any particular knot I need to use, or just anything work since there isn't much stress on it. Still not quite sure how this gauges my sag. Any videos on it? Might be a good project for Shug!
