i bought some 1.1 oz silnylon for MYOG tarp. awesome material, but expect it to be very light, very slippery, and very strong. i was used to camping tarps from the military and as a kid, this new stuff is a world apart and wonderful.
For $30 dollars you can splice everything you need for a tarp, hammock ridgeline, loops, etc. Saves a ton of money!
This item is really good for many items. I built some throw bags and bear bags for myself and some friends. This line is very strong, and slick enough to not hang on bark or branches. I recommend for everything from structural ridgelines to bear bags.

Strong, light weight cordage. Great for guylines, ridgelines, all kinda lines!
