OK, this is purely theoretical, i'm not actually doing this to my skis, but i just thought of this and i want input from people who know more about the physics of ski construction than i do....
ok so if you took a sander and sanded off a thin layer (under the topsheet) from the top of ur ski, lets say 4 inches in front of ur binding, do u think this would create a "butter zone" or simply lead to the ski snapping the next time it was flexed?
