Evening Sends Gear Review no rating given just a review

The stat that blew me away, however, is that Catalyst actually clocked in a UIAA fall rating of 7, higher than, for example, the 6 fall rating of the Sterling Velocity 9.8mm. The Catalyst is also just 55 grams per meter, which means that rope drag is never a problem, and that this rope is stronger and lighter than many other ropes on the market. I appreciated the light weight on the 15-second approach from my car to the Wasteland, saving me much-needed micro-calories of energy for my redpoint burn.

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.
