I bought this used but I'm not going to use it, so would anyone like it? There's no noticeable damage. The NUBSTER center keel, made famous by Kelly Slater's use in competitions! As an aid in a quad setup, it reduces looseness and makes top-turn carving easier. Above all, Kelly actually used it in a competition, and its performance is proven!! ■Size: Base 95mm, Height 43mm ■Material: Glass Flex plastic material Type... Center Fin
