I'm looking into using a hunters safety line this season as opposed to the strap. I know that you can buy these already made, but they seem awfully expensive given that its such a short length of rope. Tying the knots and system is very simple and I think I could probably get enough rope to make 2-3 life line systems for what they charge for a preassembled life line. Does anyone make their own? if so what type of rope do you buy?

I was looking at something shown in the link below based on the specs. I know it says not to be used as a climbing rope for liability reasons. The dynamic force of a 250# person falling 5-6 feet would be somewhere around 460# so it should work, however I would prefer something that didn't have said comments.
