I use BD Traverse poles which are a fine low budget option and I do like the mechanism never had any issues extending them in the ice or snow. My friend uses DPS carbon poles which I sort of wish I looked into, they've been bombproof for him. I know a few people that swear by Leki for the patrol grips as well. Im not a weight guy at all (bent 120s on cast) but lightweight poles are something to consider for longer days, my arms get tired a lot faster than my legs
