I know I'm alone on this, but I'm a fan of the helical, i literally have it on everything including my 3 strand construction lanyard i use at work. It can be adjusted on the fly tighter or looser so it's really easy to dial in or adjust as conditions change, works with everything beautifully. Perfect for leaving it tied too, there's a reason why the hitchhiker used basically the exact knot, very very nice on a lanyard.
I tie it a bit different, i do a slipknot for a connection point, setting how tight or loose you want it to be, and then do your loops, as many or few as you want, basically the rough setting. Then you tie a bowline with the two tails to finish the knot, which can be adjusted by working slack in/out of the knot really easily while simply unweighting it, and the whole while still tied in with it. It's also cheap and easy to run since you only need a length of cord, no eyes needed at all. A fixed leg pulley can straddle it beautifully making it a super clean and uncluttered system, which very short and compact with minimal sitback, a huge plus when running a wrench. I ran a single attachment point pulley when i was running a wrench, hitch on one side of it and the tether on the other, 1 less attachment than an eye to eye making it narrower so it fits better. These are the ends of my rope lanyard, the cheap pulley is the main one because i like the heavy snap, and the fancy one is often used as a ddrt/ moving rope system, visibly looser since i want an easier movement in a climbing system and tighter one on a lanyard.
