I do group buys every now and then of them. They are called line loks. Not sure what I have left over, but I could be persuaded to do another group buy.

Beezer good idea, I use a different loop system.
Group buy sounds good, do you have a link to your earlier group buy for these and I can check out sizes etc Julia.
A Penberthy knot?
A tautline hitch?
Knots are certainly lighter and cheaper than bits of plastic - and in my experience more reliable!
The most recent group buy was [thread=131483]this one[/thread].
They are, but they require more skill, & are not always as easy to use with gloves on. I leave my guy lines attached to my tarp, with line loks fitted, it means that I can get my tarp up in a minute or so. Sure they add a few grams to the overall weight of my setup, but the extra speed of deployment is worth it IMHO.
