I like trekking poles. They're a) lightweight; b) collapsible and adjustable which makes them easy to carry when not in use, adaptable for hiking on slopes & well suited for use as a splint; b)you can change out the basket/tips for summer & winter terrain; and c) the better ones are shock absorbing which actually does make a difference on long treks.
totally agree.
and that's why i changed over to trekking poles for some of the hikes.
