I've been using these for 5+ months now, primarily for trail running 5-22 miles in the Cascades with 1-5k vertical gain along with fast and light alpine scrambles, often stashed in my Salomon ADV12. The first thing you'll absolutely notice is the lightness of the poles along with the comfort of the cork. It's holds very nicely, I prefer it over foam- plus more durable, and wicks sweat/moisture away quickly.
The lightness was an initial concern but these have proven hardy on vague climber's trails and keeping rhythm on those occasional groomers. For longer alpine approaches I would generally feel very comfortable with these but will still bring out my BD Alpine Carbons for more technical approaches, particularly if I am relying only a pole and shorty axe.
Lastly, the straps are nice if you have a sustained moderate incline or a rolling trail but above that, you'll be using the lower extended cork and not utilizing the straps. I don't want to be locked into the pole when I invariably slip running downhill, either hurting myself or making it worse. Limited application so I mostly just leave them at home, plus one less thing to worry about dropping/losing.
All in all, an awesome set. The lightness and compactness of the set makes it an easy choice to bring even on moderate hikes- and my knees are definitely thankful for that!
