This model has volume distributed throughout the whole board nose to tail (where as the Spawn has the majority in the centre). A new simple neat feeling rail allows carving to be easy and forgiving. Round square tail giving you a little bit of area (as apposed to the narrower squash tail) and the rocker starts off a little flatter in the top third (speed) gradually builds through the middle and continues steadily out the tail giving you performance in the steep sections. Concave was a major player in testing this board. It starts under the chest medium depth and through out the tail it shallows out giving you a release when needed through turns.
