These replaced my previous (lost) set of Corklites
which did not have the anti-shock feature. I can't
tell the difference, but maybe I could if I did an A/B
comparison. Have only hiked (backpacked) with
them for about 6 hours so far. I prefer the speed
lock over the twist lock, seems more secure. But
neither locking system ever gave way.
I have no complaints about these poles.
