In reply to kate8:
I've used the BD Alpine FLZ poles, and unfortunately had 2 x poles fail (the first had the plastic coated cable fail, and the second the latch jammed inside the pole). Gave up on BD poles and currently using the Alpkit ones as they are at least cheap if they break! Build quality is definitely lower, with a rattle fit on one pole, but after a winter of use they are still working. Also the latch is on the bottom section of pole and I've a slight concern that it could be pushed in by rocks etc, but not had it happen.
I've a set of Carbon leki poles as well - v. light, but broke one when it snagged on a tree root. Leki in fairness offered a free replacement pole when I got in touch to ask if I could buy a new section and fit it. Not a new pole, but happy to get it for free!!
If you don't need it urgently i'd go with the Alpkit ones. Just don't buy the ones with the nordic grip - it's too small for me to get on over gloves (size M) and a PITA if you're wanting to go hands free for Nav etc.
Cheers!
