Christian S.wrote a review of Mammut Phoenix Climbing Rope - 8mm on November 6, 2012
Familiarity: I've put it through the wringer
This is a great rope and just to be clear, it is a 1/2 (or Double) rope. It is not a Twin, although most stores seem to lump the Double & Twin ropes in just one category.
Anyway, I purchased a set of these in 2010 for ice climbing and used them many times on both Ice and alpine multi-pitch climbs. They work great and have held up very well. By now the teflon coating has somewhat worn off, but the only way to tell is that the rope is not as "silky" as it used to be. About a month ago I had a rock (size of 2 fists put together) fall from about 75ft and hit the ledge and one of the ropes. It created a softspot in the rope where it hit so I am replacing one of the ropes. Very satisfied with the performance of this product
