Is it best to set up this kind of system like a standard two-rope rappel, with the joined ropes passed through the anchor, and the knot on the pull side, or is it best to use one of the techniques for rapping on a single strand, for example, the way you would rap with a Gri Gri or similar?

Not sure if you have heard, but there was a fatality this summer in Yosemite from guys doing a single line rap with a skinny pull cord. They were counting on the knot to hold them, and the small knot pulled through the rap rings. If you do the thin pull cord, be sure to use a back up block to prevent this.

Do you know any more details on the situation? Were they doing a single rope rap, or were they rapping on the pull line as well? I use a 10.5mm lead line and 6mm cordelette joined with an EDK to rap routes in Red Rocks however, I rap on both the 10.5 and the 6mm line. I also thread the anchor in a manner that requires the knot to pull through the anchor in order for the 6mm to slip, and I watch the rope carefully to make sure I donít get a situation where I am only rapping on the 6mm cordelette and the 10.5mm is not moving through the belay device. With that I have had no problems, however it requires you pay close attention to how you thread the anchors.

i think the rap rig was larger dia than a typical size.
