ok to answer some questions.... the nw rep just came by and dropped off my 11/12 spades and i brought up the funny issues being discussed in this thread... mainly the idea of there being 2 different models of the ski....
there is only one. the flat is (without binding) and the other is with a turn table plat... this site is for reps to purchase there demos and they usually choose to order the flat because the plate weighs too much and they would rather put griffon demo bindings on.
i asked if he had heard anything about the ski rockering itself overtime and he said no... i havent had that experience with mine either, but i would be interested to see some pictures of someones ski to which this has happened.
