Technical info:
We also tested Stereo Impact last year, but this year’s model has been changed considerably. It still has a geometry with a lot of sidecut in front and a longer radius through the back. But the tail is a lot stiffer compared to last year’s version. This is a medium heavy fibreglass sandwich. The short setback is compensated by the sidecut in the front ski.  

On snow:
This is a ski that suits a special purpose: going straight forward with the occasional skid to regulate the speed. If you are looking for a ski that neatly ties the arcs together, you better look elsewhere. The back ski is stiff and uncooperative, which makes it difficult to maneuverer. Some of the test riders also felt it swerved somewhat in the turns, which might be because you stand behind the narrowest point on the ski.  But it enjoys going straight forward at high speed. This is a ski for making 11-ens.

This sequence of numbers indicates stiffness. Each number corresponds to a part of the ski, from tail to tip. 5 equals the average
for this part and length of the ski. Lower values indicate softer skis, higher values stiffer.
