After months of climbing and miles of rock, from Wyoming limestone to Yosemite granite, the Mammut Infinity continued to impress, and is once again our Editors' Choice winner. It has a winning combination of smooth handling and a pleasant catch that's not too soft and not too hard, pleasing even the pickiest Goldilocks-like climbers. It's a slim (for this review) 9.5 mm, and as such had one of the lightest weights-per-gram of the ropes in this review. It also showed great durability, with only minimal wear after over 80 pitches on it. There may be better options in the ultra-skinny or workhorse categories, but the Infinity deserves the accolade of best all-around life line. We did slightly prefer the Maxim Pinnacle for harder sport climbing redpoints, as it had an even smoother clipping action than this line, but the Pinnacle is a more specialized line that is not quite suitable for newer climbers. We also liked the Beal Booster III, our Best Buy winner, which offered great performance at a much lower price point than this rope. Finally, if you're a newer climber or looking for something for top roping, check out the Black Diamond 9.9mm, our Top Pick for that application.
The Mammut Infinity Classic ($150) is almost half the price of the Infinity in the bi-color pattern that we tested. It has the same great handling and catch, but will have less resistance to sheath abrasion according to Mammut.
