I've taken these poles over varying hard rock use, (being as adjustable as they are, the angle of accent or decent doesn't matter!), to sand use and using in water to cross deeper streams. Their weight is awesome for carrying, and they are incredibly strong, and have yet to break after over 40+ miles of different types of climbing. I'm 5' 8" and my 6' 2" grandfather had no problem using on the way to Black Mesa, OK. I have recently used them up Crazy Peak MT, and they save the knees so much on the decent. Are about $130 but I would say worth it all, especially if you carry them on accent while using an ice axe. Worth every penny in my opinion.

At first, most people I met walking with poles only started using them when they developed joint problems that became too much, but over time, more and more people started using them even before that. So, although I haven't had joint problems yet, to prevent getting them, I decided to buy a pair.

Since then, I've used them extensively on all sorts of terrain. They held up fine, and I learned that it not only made going downhill easier on the knees, it also helped a lot when hiking with a big pack on easy terrain.

I really like the simplicity of the flick-lock adjustment mechanism, and having seen other people struggle with screw mechanisms inside the pole, I'm quite happy with it. Very easy to adjust and when it's locked, it stays locked.
I've put them through a lot of abuse, and last summer, the bottom part snapped. However, I doubt if any other pole would have survived that ordeal: I was moving along on a snow covered boulder field and the pole got stuck deep between two rocks, and because I didn't let go in time, my full weight was pushing against it. That would be the end of most poles, I presume.
Back in the store, I ordered a new replacement part and now it's good to go again. However, I'll try not to hold on again when they get stuck.

The set of both poles are lighter than one of my previous BD poles. I like that they flex a little more. So when they do get stuck they don't break right away. I also like the grips on the shaft below the normal grips. Just choke up on the shaft if you have to move up and /or over rocks or high steps. You pay for the light weight, but if you have been doing any sort of hiking and mountaineering you knew that you were going to.
