After this weekend's hike/climb, during which I used a heavy staff for a walking stick, I definitely need some trekking poles if I'm going to continue hiking and climbing, and also for snowshoeing, which I'd like to try this winter. I did some recon at EMS today, and it looks like I want three section, spring loaded-anti shock and either foam or rubber grips. Am I on the right track? Any makes models that stand out, or ones I should avoid?
