The harnesses I have used we clipped into the figure 8 with a Krab on one attachment to the harness. Not fiddly at all. Double the rope then tie figure of 8 (with practice you can do it one handed) then clip the loop formed into the Krab. EDIT to add you could always clip two Krabs into the loop.

In the region of 60+ years. It was a great encouragement not to fall. 😁 Named after Don another of the climbing greats.

That is another use for one when tied in a single thickness, when climbing you tie it with the rope end doubled back forming a loop beyond the knot. I suppose it should possibly be called a doubly figure of eight. EDIT to add IIRC it is a figure 8 on a bight

When I started you tied the rope round your waist with a bowline, then when harnesses came in we used a bowline, eventually figure of eight became popular but why I have no idea. Can you tie a sheet bend? Look carefully at a sheetbend, it is just a bowline tied in a different way.

Same here apart from the laptop being a Toshiba. I have had no problems (so far !)
