I recently purchased my very first pair of skis. It is Salomon QST 106 (181cm). One problem is, there are some graphs on its base, and it makes the base not as smooth as skis I have used before. There are very obvious lines between two colors when I touch it. I am not sure if that is normal on this particular type of skis. If it is normal, would it not decrease the speed when sliding on snow? If it is not normal, what should I do about it?
