Poles haven't come with me on any recent (3) trips. They won't be going on my next one.
I'm really not sure at this point if they do anything positive for me or not. I used to feel they helped me keep a better uphill pace, but I can also keep a good uphill pace without them…
As for downhill, I'm not sure they give me any advantage over going without.
???
Personally, I've never thought of them as an aid for balance, mainly just for pace.
I will say they're really helpful if trekking on snow a lot…
I sort of feel like they take too much attention.
But basically, I'm just tired of having stuff in my hands all the time.
At the end of a 20-30 mile day, with or without poles, I'm tired.
I can identify no quantifiable difference in my hiking…so why bother?
Also, coming from a running perspective, they're beginning to make little sense to me (especially when carrying a really light pack). As a distance runner, I want my arms loose, relaxed, moving naturally with my stride…not pumping and pushing with my hands clenched/gripping something. Why should it be different for hiking efficiency?
To each their own.
