If you want fast and convenient then these guys are the ticket. They weigh almost nothing and break down in a jiffy. You just snap and pull and, viola, your pole is ready. No fuss with the adjustments at all. Worlds better than the older Lekki poles I've used.Some people like the poles whose length you can adjust, but with all the elevation changes I think it's easier to just go with one length and adjust your poling than to be changing the length all the time. If you have more trouble going up than down, get the poles slightly shorter. If you have more trouble going down get them a little longer.They are slightly heavier and sturdier than the original ones Black Diamond made. Those would be better for trail running. These are light enough that I'm willing to make the trade-off of a few ounces for greater durability buy YMMV. Also note that these are not adjustable in length. That's another trade-off you make for ease of use and light weight.
