Here's the skinny on the WLseries. They are designed to be an all terrain freestyle ski. This means we blended the best features from a pure freestyle ski and an all mountain ski and put them into one package. The flex is stiff enough to handle all mountain, but is still butter friendly, the sidecut has taper to it for turn initiation, but the setback on the sidecut is 0, meaning you are very balanced on the ski for spins, rails, etc. Essentially this is the one ski quiver.
Hope that answers your question.
