Tough, durable, won't twist, get some.
I've bought a bunch of these in the 17cm size to donate to a super-steep route with a few hard clips. They are tough as hell, so they withstand abrasion well. They are wide enough to grab in the event of an emotional emergency (but please, never grab a draw when you are falling - I don't want pieces of your finger stuck in the draw if I climb that route after you.)
They are wide enough to resist twisting, unlike the spaghetti-thin dyneema dogbones that seem to be in style these days. I dig em.
