Just plain better.
I use a combination of these and some Wild Country Dyneema slings with my draws, and these are hands down better. They honestly don't weigh any more, are thicker and don't twist, and the "String" rubber piece on the end is fantastic and replaceable. These combined with a Camp Nano 23 rope end biner and a Mad Rock Super Tech Straight Gate bolt-end biner make a beautiful draw that is only 2.4 oz. They're the same price as the BD dogbones, and the big rubber attachment significantly better, so don't hesitate.
