lemon: yes, you can use trekkers w/ dukes. i wouldn't recommend it though, since you'll have to get out of the bindings to switch modes. :eek:
chris knight: you don't get it. stack height is good for you. better angulation. and, since dukes are all freeride oriented, think about skinning in super deep pow. the stack height will make you tall enough so your head is actually above the snow so you can breathe. :nonono2:
