my bases were flat, but i was getting some base repair work done, so i felt it was just good to get it all smoothed out.....if anyone is going to get their skis tuned for the season, i'd recommend a 1 degree base, and 1 degree side edge bevel. If you are a bit more aggresive, go with a 1 degree base, 2 degree side bevel, but it require more effort and maintence to keep it sharp. My skis last year, in the beginning of the season at least, had a 1 degree base, 3 degree side, which holds pretty well on ice I went with the 1:2 this year, gunna see how that feels
