After almost 10 years, I finally had to replace my Black Diamond Alpine Carbon Cork winter poles. I have been incredibly happy with Black Diamond poles, however this time I decided to give the MSR Dynalock Ascent Carbon poles a chance - for no other reason than to try something different. What I like about them: they are very light, they break-down super small, they have 20cm of adjustability, and the locking mechanism can be tightened without tools. All I hope for now is that they stand-up similarly durability-wise to the Black Diamonds... we shall see.
