This year CWB has introduced the "Capped Fin System" where the center fin is only a partial fin-for those who prefer a looser feel. However, for those who want a little more bite, The Prodigy comes with two different size "capped" fins that can be bolted over the preexisting center fin...now that's some serious innovation. In addition, the Platinum models feature a lighter core construction with fiberglass rods running the length of the board for greater pop and more acceleration on landings.
