Billy bimble with a couple of twists; firstly a new "Look!-no-harness!"[tm] suit what I have commissioned for a return to a rippy cave in Eastern Europe and secondly a no-metalwork rigging trial. Both worked splendidly. Billy is a happy boy! Shall have to return with a tame photographer so as to share the weirdness.
Also on their way are further retro mods to make life comfier, too, field trial(s) notwithstanding.
