I'll start off with a couple.
Harsh: on firm conditions, picks up a resonance and sends a vibration through the ski which caused the edge to shake, chatter right off the surface and feels uncomfortable from the foot where it starts and all the way up through the knee. A harsh ski feels like is is pounding the snow, hammering the edge, hollering in your ears.
Damp: In all conditions, the ski absorbs vibrations produced by chunks of set snow, washboards, ruts, and chopped jagged surfaces without magnifying them, then reduced the vibration by sending it through a layer of rubber or similar nullifying medium. A damp ski does not resonate, it does not vibrate, it does not chatter off the surface. A damp ski feels close to the snow, down in the snow, glued to the snow, and does not send vibration and chatter up your leg, but rather sends a solid, clear sensation into your foot that makes reading the terrain with your feet comfortable and precise.
