Do you think it would be better to get one of those pocket sharpeners to help fix up edges or like a rub on wax to help fix up the base? Wat do you think would be more helpful to overall riding?
What you want is a small edge stone and a couple chunks of wax. Keep them in your pocket or in the car if close by the lifts. On a powder or soft snow day, wax is the more important thing. For an icy or hardpack day, the edges are more important.
