That sounds like it'll make some great slings. Where did you get it? The stuff I use is made of the cheapest sisal cord ever. That's probable cuase I buy it at the cheapest dollar store ever. But I can't find anything better anywhere. I think part of the problem must be that no one around here uses natural cordage for anything.

I use 1/2 cm diametre cotton cord which I buy at the local home depot and although I only get 15 metres or so in a package, I only use about 2 metres per sling, so it lasts a while, and being pretty thick, it tends to outlast some of the sling pouches. Although, I suspect that the leather pouch I have on my cotton cord sling will well outlast probably not just the cords but my shoulder as well. (Just went slinging today for the third time in two days so my shoulder is a little stiff)
