WildBANimalIn a side by side test, I felt like the Adrenalines gave the best "feel" of the ski out of the main plate binding brands...
The Guardian/Tracker bindings seemed funky, and Dukes, while they're not bad, still don't always feel that great - especially after a few years of actual sidecountry use.
The Adrenaline seemed to be the best design out of the three if you really want my opinion. Plus, they're lighter if I'm not mistaken? (not that it matters as all of them are heavy)
