had the 60 meter, didnt like it. the half way threads quickly wear and over a few months they are no longer visible (somehow the strands either fall out or break off or something), so it is very hard to see half way. the rope also gets pretty stiff, and doesnt handle as well as I would have hoped. all in all i would not recommend it...
I like them quite a bit, I'm on my 2nd 60M 10.2. The marking threads do wear out pretty darn quick but the sheath itself is pretty durable and the rope handles very nicely. I would definitely buy another.
Best ropes I've ever used. The threads do wear out way too quick though. Durability, handling, lack of tangles and twists, all exceed performance of comparable ropes I've used in the past. My favorite is the 9.8. It's not as bomb-proof as the big line, but it has still outlasted any other 9.whatever I've used. Tons of rock (including a week in the desert),sport, trad, ice, easy alpine, and the dry treatment was still kick'n for a week long trip ice climbing in warm weather. When this dies I'll buy another for certain.
