Rock and Ice Gear Review rating 4/5

The Diamond is two to three grams per meter heavier than some comparable ropes, and has a somewhat stiffer hand, but the increased durability seemed worth the extra weight. I didn’t experience any unusual twisting, even when new, and the diameter seemed right on the money. (Sometimes ropes will be assigned a diameter but seem thick in the hand, especially after heavy use. If anything, the Diamond seems thinner than it’s given 9.4 mm, more like a 9 mm rope I compared it to.)

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
