This model is a variation of the Hi Performance Hybrid. The rails are stepped down on the deck so it still has performance rails and bite. With a slightly more pulled in nose the bottom runs single concave from the nose down most of the length of the board and blends into a double concave V from the fins out the tail. The bottom rails are beveled also from the nose down most of the length and flattens out where the V begins. This board is fast and loose so the double wings pull the tail in for precise turning and the swallow tail gives the hold and drive when you need it.
