Late season season on our narrow test skis. My wife and I borrowed Head Supershape i-rally skis, size 170 and 163 cm for about one month. The skis engage at the beginning of the turn, hold their turn shape really well, and are super easy to get on edge. We varied our turns from short radius to wide open turns and the ski were locked throughout the turn. My wife worked on her lower leg/ankle angles, lower body form and received feedback from the skis, unlike her 90:and 100 mm wide skis. As many posters mentioned, learning on narrow carving skis was an eye opener. We will probably purchase e-Rally skis,156 and 163cm with protector bindings. We used the skis on firm and soft groomers, intermediate bumps (hard and soft), and end of the day skied out groomers in B.C. On powder days, we opted for wide skis. She is now skiing the fall line in gladed trees and fairly steep deep snow with snow covered bumps on advanced runs. FYI, my wife skis about 40-50 days per year.
Based on our limited experience, the Supershape skis are outstanding - again we have not compared similar skis to other manufacturers, such as Stöckli. Kastle. Rossi, etc. I do not want to open a can of worms, but should we consider Stöckli skis. A good friend, former Canadian National team bumps skier (he skis Kastle), thought the Stöckli skis were worth the extra money. I am not so sure about his advice, and wanted gentle and kind feedback for the Skitalk community without too much Stöckli confirmation bias.
