Rails will affect any ski. All this bullshit about the pipecleaners exploding on rail is reduculous. The PC's have the same edges as the Ar6's and T-Halls, yet a slightly softer base. Dont worry about it, they will be fine. Any ski after time will fall apart and the edges will crack. Its just how it is.
