I got these poles last year for Telemark skiing. On the way down on my first trip the locking mechanism jammed and the mechanism detached from the pole when trying to fix it. So one of the poles is now stuck on 100 cm... In addition to this, I lost one basket - the locking device for baskets is not very good either. Luckliy my local sport shop had one extra basket, as you can't buy extra baskets from MSR.
So I got Black Diamond poles with flicklock - and they are way better! The denali III was a waste of money for me. If you plan to get them I would strongly recommend to be careful with the locking mechanism, and perhaps not to use them for high energy activities like Telemark/AT skiing.
