Familiarity: I've put it through the wringer
Just got back from summiting Rainier with the puppy and I have only good things to say. Its as thin as you can go while still safely using a single rope, which is ideal for glacier travel where a crevasse fall is a possibility, but a lot of technical ice climbing is not on the menu.
The water treatment is bomb proof, and two storms + a day of dragging over wet snow did not even begin to faze our little lifeline.
For really bottoming out on weight, this rope is clutch. Remove it from bag and the supple ripples will rip your heart right out. Plus, none of those pesky mountaineering coils to deal with when you're flaking for the first time.
Edit April 2015: Have now used this for vertical ice as well. Still only great things to say. Climb on my friends.
