Good project Ryan.
The latest generation of tech race and race-ish boots are quite amazing. The warmth and waterproofing advantages are enormous, especially for multiday stuff in crappy conditions. My own objections to the system, and continued use of 3 pin bindings and duckbill boots for nordic touring, are twofold. First, the lack of metatarsal bend in the boot and any friction in the binding system results in sub-optimal kick during a diagonal stride. I'd spitball a 30-40% reduction, average, depending on conditions. Obviously, not so relevant when breaking trail. Second, hiking and doing camp chores in plastic boots, even heavily rockered, short BSL race boots, sucks. My favorite routes over on the east side of the divide always seem to feature a decent amount of hiking in wind scoured areas.
