yea I've had enough with the slipping, I'm putting 2 screws in each adjustable connecter to make my poles permanent at the height I like them.
My thoughts are.... I never adjust the height on my poles, I like them the same for ups, downs and everything in between - I may just use them a little different like palming mostly for downhill but I like the same height. I got my poles in May and hiking every weekend I'd say there in my hands 98-99% of the time. Even if I do a road walk and I'm not using them I'll just hang onto them and then with the wrist straps I have them on and dangling as I take pictures, smoke my pipe, eat a snack, ect. If I needed to strap them on my bag I still could vertically, I have them a little over 3 feet which is about up to my hips. I don't see me ever strapping them to my bag as I love them and use them constantly while hiking. I think I'd rather compromise the adjustable factor to make 100% no slip issues and not worry about it.
I have the Fizan 'compact 4 (169 grams)' trekking poles and it took months before they slipped at all and it's not that they constantly do. It looked like it was only the lower connection so I screwed that one but I noticed a little more this weekend so I think I'm just gonna put screws in all the connections now. I don't go crazy putting all my weight and hammering the things either - plus I'm a light, skinny guy. I think it mainly happens when the poles come down on a rock or something and it doesn't have any give like in the ground... but still I'm not excessively smashing them into rocks or anything - I'm not using any more force then the first few months with no slipping. I pretty much just try to even out the load between my legs and my arms with the poles.
Any thoughts or concerns this might cause besides losing the adjustable factor?
