Never buy again
I've been a Mammut rope fan for years, with this being the 6th purchased for personal use (bought several for guiding). It seems well made and is durable, which is a plus. However, the Flash is unlike the others. It is super-stiff, doesn't knot or handle well, kinks like crazy, and has picked up more dirt and black aluminum that wouldn't wash out. Maybe it was a batch thing, because I can't believe it's from the same company. Hoped that it would soften, but after about 20-30 pitches it is still like a cable. Always loved how Mammuts handled. CAN NOT WAIT TO RETIRE THIS ONE. I don't think I've ever been as unhappy w/ a piece of gear. It ranks up there with climbing shoes that don't fit. The fact that I bought a 10.5 proves I'm old school, but I wanted something bomber, which it is.
