I know it's semantics but I feel that the issue, as some have mentioned, of having to work harder in my case was not due to drag. Quite the opposite. At the end of my set I did not feel I worked harder but felt an over all fatigue. Makes sense, I skied more passes (no falls or misses). Before the VW (this spring) I felt like I was working harder but just parts. Lower back, back leg, fore arms all due to my inconsistent skiing. Those part(s) of my body caused me to end a set. I was working harder to maintain balance and technique. At the end of a set, the part was fatigued not an overall tiredness/fatigue as felt with the VW. If the consistency stays with the VW all my correct muscles get the workout instead of overloading certain ones here and there based on inconsistancy to the point of stopping.
