First time winch owner and I went with Warn Spydura Synthetic Rope. The manual says to use a flat surface and moderate brake pressure and make sure one layer of rope doesn't sink in to the one below. I was planning on either using my driveway or street as they are both on a pretty good hill to wind my rope on to the drum. How critical is this "stretch"? Certainly doesn't sound very scientific. Beyond making sure the rope does not overlap or one layer sink in to the other, is that all I really need to worry about?
