@Noodler, more info on the riller bar? Is this the same as those brass structure tools that SWIX sellsPotentially may work, but depends on just how wet the snow becomes. Note that the stones on the SkiVisions tool "tear" at the base (like sandpaper) whereas a riller bar imparts the structure with a cleaner cutting and pressing action that doesn't abrade the surface of the ski bottom. Abraded ski bottoms are slow.
