Anyone beside Pacerpole http://pacerpole.com/ making ergonomic poles? Reviews say they're far superior, a reviewer said a 25 mi hike with them is like 20 with other poles. Anyone try them? Site makes a lot of sense (except their disingenuous rationalization that their heavier weight is irrelevant when they're planted, they must know it makes a big difference in footwear.) Would be a nice drop.
