Own both. Leki owned first and began AT with them. They are a good pole. But went with Pacer poles for one simple reason: pain. I am 78 and still out there. I could not hold on to the Leki and not have pain in my thumbs. Totally an aging thing. If not hiking, I am fine. Then, after awhile with the pacer poles, the different ways to use them becomes a muscle memory thing and going back to standard hand hold felt weird. Pacer service is great. And twist lock is fine if you separate the pole, wash crap off, and air dry between trips. If "out there" for any length of time, I just separate and wash as often as I can. Also, I go with an Heximid solo tent when not hanging. So I have the set up pole with me. And it fits.
