I’ve used these poles twice now, after trying quite a dated (but tough) pair of MSR poles from a friend. They are nice and light, the flick lock is easy to use and tight, and the tips were solid on ground as well as rock. Telescopic adjustments were perfect for my height (5ft6). I mainly mountain hike at the moment, so great on the way up for balance and force, and a saving grace on the way down over tricky boulder fields, rocky descents and the odd creek. My friend’s poles (not Black Diamond) snapped on the way down and mine held out no problem! A trail runner maybe want something even lighter like the distance range or carbon, but I like the feel of some sturdiness to it with the terrain I’m hiking. Also, the extended grip material is so handy for quick changes in incline, a great feature!
