Has anyone on here made their own lifelines with climbing rope? I want to start installing these on all my stands, but at $30 a pop the HSS rope is a little steep given the number of stands I have. I am thinking of buying some good quality climbing rope and making my own Prussic knots. Has anyone tried this? Also, I realize that you can't put a price on your life, but if someone learned how to properly tie these knots and use good quality rope, I don't see how it would be any less safe that the HSS Lifelines. Thanks in advance.
