What knot to use when joining cords together so you can rap down a few pitches?
How do you get past the knot? gulp
I am Knot a "Big Wally" sort of guy. The few times I have needed to do this, we used double fisherman knots, my partner left the ends long enuf to make two looped steps. When you got to the knot, you stuck your feet in the loops, put on a prussic (we didn't have jumars) to take your weight off your device, undo it, than reclip in below the knot. The loop steps really helped to get your weight off and steady yourself while swinging, rotating around in space.
And something else. What is the best knot to use when you need to tie ropes of two different diameters together, like a 5/6 mil accessory cord and a 9.5 lead line?
