Black Diamond just recently started making ropes, and we were excited to check them out in our updated review. We chose to test the 9.9 mm rope, as it was already a top seller on many outdoor retailers, but they are making a full-compliment of ropes from this one all the way down to 7.8 mm half ropes. We were happy with the handling and performance of the 9.9, and look forward to checking out the 9.6 and 9.2 mm ropes down the line as well. The 9.9 that we did test was a little heavier than some of the more performance oriented lines in this review, and as such it didn't score quite so high as them. However, we were impressed by the great balance of soft catch but not too stretchy for safe top roping, and the thicker diameter makes it a great (and safer) choice for newer climbers. It's also available at a great price point in shorter lengths specifically for indoor use, making it a clear choice for our Top Pick award for Top Roping and Gym Climbing. For a more versatile all-around rope, check out our Editors' Choice award winner, the Mammut Infinity. We also really liked the Maxim Pinnacle, and gave it a Top Pick for Sport Climbing award.
The Black Diamond 9.6mm has slightly more dynamic elongation (34.2%) and a slightly lower impact force rating (8.2 kN). It also comes with the Endurance 1x1 sheath, as opposed to the Regular 2x2 weave on the 9.9. This line is available in 60 and 70 m lengths, and also with a FullDry treatment (core and sheath).
