I just got a new pair of Fischer the Curv DTX's. I learned a while ago to always question the factory tune. Sure enough, the base bevel varied from 0.5 to 1.0 intermittently along the length of the ski. The bases were pretty flat. The side edges weren't real sharp and probably about 2 degrees. They skied OK, but not as good as I expected. I then put a very sharp 3 deg. side edge on them. That made things worse as the skis got grabby and hooky. Took the gummie stone to them and back to OK. I will need a base grind to fix the base bevel and I expect them to work great afterwards.
I use magnifying googles, a led light, a straight edge, and feeler gauges to check the base bevels. I check the side bevels by holding my side edge file holder up to the edge and eyeballing it. I will start a thread soon and take pictures and show how to measure base bevel, It is pretty easy to do.
