Depends how much you disaster stuff/land hard on rails really. If you dull them from the start they will last a bit longer, still nothing compared to most park skis though. Its a real problem. Great skis otherwise though.
Sorry but what about stiffness? I kind of dont want to buy them because of the edges but I think I will use them for boxes and not so many rails and hopefully they dont break. For people that have broke them, how long did it take, and how hard were you skiing them?
