thats because price wise, the duke is pretty in line with other top end AT bindings, whereas marker is kicking themselves in the ass by trying to sell the jester for 329, when its competing against bindings like fks, p/px 12 and 14, and salomon S914/916s, that already have a solid backing from the consumer marker, whereas the freeride community has completely bashed marker in the past. it's gonna be an uphill battle for that binding. i've skied it, and it skies really well, but i am not sure how i feel about the toe piece in that it doesnt really have a true vertical release.
