I am a bruiser when it comes to trekking poles. Over the last 8 years since I began using them, I have broken 11 sections of 3 different pairs of trekking poles (yes, for those of you doing the math, I broke some pole sections more than once, and repaired them in-field with a piece of hacksaw blade,duct tape and a tiny gasket).
Eventually I found a pair of poles I couldn't destroy, Leki's Super Makalus. However, I often managed to jam the sections enough that I couldn't collapse them, which made for extremely awkard packing when hitching into a town and the like. About two years ago, I landed my first pair of Black Diamond Contour Trekking Poles at an REI scratch and dent sale. They were listed as "slightly bent". I figured I would probably destroy them quickly, but for $20 they were worth the chance.
I have since backpacked over 1000 miles on these poles and except for replacing the carbide tips, they are as good as new. I LOVE the flicklock machanism. I've never had any problems collapsing or lengthening the pole section with it. I know some people have complained about the push-button binary lock on the lower section, but after the first half a dozen tries, I became accustomed enough to easily use this as well.
They are light, with a canted handle, which I believe is a key to avoiding the carpal tunnel syndrome I developed using straight-handled poles on the AT (back in my pole-splintering days). At 17 ounces, they are not the lightest poles out there, but they ARE the lightest ones I've not destroyed. I recently bought a second pair just in case BD chose not to produce them in the future.
