Nice system, but bulky, not practical for hooking onto your belt. I use doubled assenders and a pantin for DRT. I can use them for long pitches when moving around in the canopy while working.
OOPS, spoke without thinking! I use the pantin quite often when on the loop & SRT. DRT is still footlock. I have started backing it up with a Klemhist under the assenders if there are any twigs in the way.
