Fine work Gord. Liked the music.
What knot are you using for rigging down the limbs. Looked like something like a bowline. Seemed that you were taking two turns around the limb, then clipping back to the loop in the knot. Is this so? I usually terminate to a biner with a scaffold knot, but it would be in the way for the double-turn and clip method that looks so fast. No slings needed.
After you get out of your friction saver, are you just going on a DdRT for the rest of the climb, even though you don't have any crotches to use if with, effectively a second flipline? Do you use your adjustable friction saver to choke the spar? The reason that I ask is that I like having an emergency lowering-out system.
