One of my partners used this last fall season. I will probably switch my kit over to it as well. It’s really svelte, albeit a bit emotional the first couple times you bet the farm on that one piece of 6mm cord.
I've used a normal piece of 6mm for maybe 5 years, though I've never used it as my primary attachment point. I initially started using it as my 3rd attachment point for positioning when I have a camera and I'm jugging. More recently I've used the 5mm to attach to my top jug and then an 8mm to attach to my bottom. I only do this when I'm trying to go light.
I personally wouldn't use 6mm Pur or Powercord unless I was trying to go super light on an alpine climb. For normal big wall use or multi pitch use I don't think going skinnier than 8mm is worth it.
When people replace the cord what are they using to attach it to the harness? I did this last year and used a competition knot which I think worked quite well, but was wondering if there was a better option. I had it set up as two separate lanyards rather than one two lanyard unit (which is what I wanted) so really interested in a method for attaching a single lanyard rather than a double.
Edit to add. I replaced with 7.5mm dynamic half/twin rope from decathlon, worked well imo. I did test it with some pur line at home and it seemed to work. In fact it seemed to work with 4mm accessory cord, for my bodyweight only tests anyway.
I swear the dimensions on the evolve adjust have changed over time. I couldn't get my new-ish one to stick with smaller diameters that others had good luck with. 9mm static is as small as I can go with mine without slipping. Also, the original chord it comes with now is thicker than the rope in the old ones.
