tonyyarusso: "I'm actually curious to hear your review of their bindings specifically, for possible use on other skis."
I like and prefer the universal binding sold with the skis over a 3-pin nordic system, but only because the binding allows a wide range of boot types.
The binding installs with 3 screws (#3 Phillips, not Pozidriv), with the hole pattern being the standard 75mm nordic/tele norm.
Altai sells a binding for shoe sizes > 14 (35cm) mens called the Pivot, which is also marketed as slightly better for touring because the pivot point is nordic (behind the ball of the foot).
