I have used those MoutainSmith hiking poles every nite since I got them. At diff. widths even. I have a set of Brandon's hiking pole tips, and for now, just screwed the one on the handle screw, and leave the tip ends of Brandon's for now in a baggie stuck in a pack pocket so I don't loose them. I see nothing wrong with the poles what so ever and they work at any width just fine. Been using them all this time unlocked too until Paul found that video, so now they are locked. and working just as good as unlocked. Can't wait to get out and do a hiking trip when I get thru my bad work schedule right now. Pretty much tied down with work for now.
