I have had some of the Figure 9's for a while but never had any small diameter rope. At the campout last weekend I bought some of Ed's Orange Spectra cord. Tonight I tried the setup on my tarp. I tied a noose knot on the end of the rope going thru the tarp end and put the Figure 9's on. I have a lot of rope on each end right now. I setup it up with no problems. I pulled on the rope just to make sure everything held and it did. Quick and easy for sure.

My tarp is the 9x9 Sportsman Guide tarp so the ridgeline is approx 12'. Question though, how much rope should be on each end of your tarp?
