I'm surprised how many people have one. I have one that i try to use on longer hikes, but here in Texas the topography can be so flat that there isn't much point to it. It has a carabiner on the strap which is a great feature for those long flat stretches where you don't really need anything. It was good in big bend but mostly a pain on the 4C trail.

I opted for the Leki photo with the removable top knob so you can "add a scope, camera or a gun mount". Although I haven't ever had the need to do any of that. Can't say it was worth it.
