In reply to Pete Potter: All I can say is having had Beal Icelines, which I used in very similar conditions to both my Mammut Phoenix and serenity, the Icelines were at the end of their life in a year, where as the Serenity has had a hard hard life, being used for everything from trad cragging, to scottish winter, to climbing on the super rough granite in Yosemite and the meadows (everyday for 3 weeks), the alps on alpine routes and it is still going. My icelines fluffed up in a matter of weeks, one sheath abraided in a single short toproping session (I know - don't hate me
) and the other almost cut through during an epic in the Gorms. To look at the Mammut you'd think it was well used but not have any doubts about it's strength - I can't say I felt the same about the beals. Yes they are specialised but they really have their uses, especially when you are doing big walk ins... not a sport rope unless you're going for the super hard flash, but then I didn't need to tell you that right? Used as a double it's also great...
