Makin' Life Simpler
"... give you much more security than a daisy's bartack loops and more convenience than a sewn runner." That says it all really. Do the majority of climbers need a PAS? No. Do I even? No. But it makes life a heck of a lot easier and it's safe. I tried the whole sewn runner thing, with it girth hitched and some overhand knots in it for adjustability, but it's a pain in the ass, and shorter than a PAS. The PAS racks up relatively clean whether you use one 'biner on it or two. I have mine between my legs and under to keep it out of the way and prevent it from snagging. I use mine to help me clean a route, set up a rappel, and anchor into a belay.
