I need a third pair of trekking poles for those rare times when both my son and daughter (young adults) come on a trip with me.

These would see very little use (maybe 5 days every year or two), so long term durability is not critical. Well-used poles that are taking up dust on your gear shelf would be perfect.

If fixed-length, they'd have to be 120-130 cm.

I like Black Diamond flick locks, but beggars can't be choosers: I'll consider any functioning pair.

Thanks.

(FYI, I'm new to BPL, but have posted for years on the backpacker.com forums and nwhikers.net.)
