Technical info:
Stereo Impact is a fibreglass sandwich with rocker in the front ski and a very low and acute tip. Low camber and flex below medium stiffness. The sidecut radius is short in the front, and relatively long in the back ski.

On snow:
Impact is Stereo´s big mountain ski, with long rocker in the front. It appears like an unconvincing copy of many of the other skis in the test and similar skis we have tried in the past. Stereo´s Impact is at its best in optimal conditions off-piste on soft snow. But as an allround ski, and after testing on many types of snow, we think it is too unstable and too slow in the turns, and the edge grip is poor compared to the other skis in the test.
