Rating: 4 / 5
Had I experienced the 'clicking' problem that Jason had, my score would have equaled his. Fortunately mine make very little noise, but I prefer a rubber tip cover due to the soft trails I hike most of the time. Maybe the tip-covers masked some of the noise?
The flick-lock system is far superior to twist locking mechanisms of other adjustable pole sets I've used.
The binary lower is good, but is difficult to engage while wearing gloves.
The straps are very comfortable, but mine are starting to fray after 15 months. (About 200 hiking miles of use.)
In use, I leave the flick-locks set, and only use the lower binary to shorten the poles for travel or packing.
-1 point, for weight . . .
Overall, I have been very satisfied with the Spires, however I am working on a set of DIY carbon-fiber fixed-length poles.
