Ok, so this isn't really a new topic, but so many people use trekking poles and I think the superiority of cane grip poles is so dramatic, that it's worth another post.
I am certain that very few of you have really, seriously tried cane grip poles. Good trekking poles aren't cheap and you've been told by "experts" that vertical grip poles are better, so you have been unwilling to try cane grips just to see for yourself.
So, very few of you, maybe none of you, have tried cane grip poles and, probably, most that have, have adjusted them, incorrectly, the way they would vertical grip poles.
You can't say they aren't as good as vertical grip poles because you haven't given them a fair test.
Be honest now.
I have very good Leki carbon fiber vertical grip trekking poles and a second, cheaper pair of Mountain Smith poles. I've used them on some long, hard hikes. I do know how to use the straps. I don't understand why anyone would just assume that I don't know how to use the straps. I used to go up to a Nordic center a couple times a week, during the winter.
But the new Leki cane grip poles, adjusted correctly, are ten times better than vertical grip. They are more ergonomically correct and allow you to push down with greater force. The correct way to adjust them is so that your arm is only bent about 20 degrees. I let my arms hang by my side and adjust the poles so that the grip is about even with the wrist.
Is it a matter of personal preference? Probably, but without trying cane grip poles, adjusted the way I say, how can you know that you wouldn't prefer them?
