I do t tour so I'm probably not the best source... But frame style bindings like dukes/barons, guardian/tracker, fristchi freeride, mfd alltime plates, will all be safe on cliffs, drops, jumps, and lift serve skiing. The big drawback to them is they're substantially heavier and you have to lift the heelpiece with each step causing fatigue Frame AT bindings will be best for shorter tours where having good release characteristics are critical. You can use regular boots with these and a walk mod boot helps. . . . . . . . . . . . . . . . . The other alternative is Tech bindings like dynamics or plums. You can't use conventional boots with them as they use a different way to retain the boot. They are however far lighter making for easier tours. They will also handle decent cliffs but they don't have the same elastic travel that a frame AT binding would have and they don't have the same release characteristics, potentially making those cliffs a little dicier. They also can't be used for frequent lift serve days as it has been shown that the bindings and boots tech inserts wear rapidly under the pounding loads caused by hardpack. . . . . . . . . . . . . . . . . Sounds like what your looking for is a frame style binding though so maybe take a look into the Marker Dukes and Barons, or the Salomon Guardians or Atomic Trackers, or Fristchi Freerides. You could also look in to MFD all time plates but their cost, weight penalties, and performance, just seems like it would make more sense to buy a real touring binding. Hope this helps, sorry for the period segmentation. iPad won't let me post with paragraphs. Damn HTML&iOS...
