It appears that Black Diamond is beginning to use the 10mm Dynex more and more. They aren't using the nylon dogbones in their quickdraw combinations anymore. I have some of the nylon ones as well as some of the Dynex. I feel that the wider slightly stiffer nylon ones are more stable when clipping the rope into the bottom biner, because the Dynex slings tend to twist more easily. They are both rated at 22kn so you can't go wrong with either one. Rubber inserts on the rope end are a must to have on all 'draws. They hold the biner firmly in proper orientation and are available on both the Dynex and nylon. Overall-Great product from a great company.
