Is it ok to use lightweight polypro for tree huggers in a marlinspike setup? I bought it 1" polypropylene webbing at a fabric store which showed no rating. It weighs 2.01oz for a 12'8" length (0.1587 oz/ft). I weigh 150 and they held up for the 15min I tested them out as full suspension lines but I don't know about long term. Thought I'd ask.
