So far only a few longer hikes on mixed terrain. They are sturdy, limited flex, the light weight is fantastic, and look great. Only caution is the carbon sends a little more impact on harder surfaces than my old aluminium poles. Oh, and buy the rubber hiking caps at the same time as the poles. The ones they come with are protective caps, not walking caps. Off to Larapinta next month, so will see how they perform over multi days.
