Out here we have a severe lack of trees so length can be crucial to get you to an anchor. Now that I think about it, I better go with 100?
I was glad to have 100' last weekend. I was in a pretty tight spot that I felt I need to winch to avoid going over. To get a straight line pull I needed probably 90' of the winch line. there was a good size clearing after this hill climb. I'm actually going to make the first rope Custom Splice sent me into two extensions. Based on my youtube research, it is pretty easy to splice winch rope.
