I picked up a pair of the Montem Ultra Strong polls this spring. https://montemlife.com/product/ultra...rekking-poles/ It took a while to get the tension dialed in (tighten when clip is open), but no slippage now. I really like the cork hand grip. Very strong and light (19.2 oz) for the money ($50). The only think I don't like is that the screws rust. When I wrote the company about it, they said I need to take the polls apart and dry them -- does that happen with other brands?
