I picked up a pair this season, and you notice a huge difference on ice/hardpack with the magne-traction edges, so far i haven't had that big an issue with durability, and I've been teaching lessons w/ young'ns running over my tips and tails, and it hasn't hacked them apart at all really. With the sandwich construction you'll just need to avoid tapping them on the lift to get snow off :P it rapes the edge of the top-sheet, other than that their a good ski, pretty stiff with a lot of pop if that what your into.
People ask me where i see myself in 20 years,
I don't even know where I'm gonna be in 20 minutes.
