4A
A well-balanced fin with a full base linked with the tapering, moderately flexible tip provides a solid amount of drive off the bottom, and  responsiveness through arcing turns. Designed for both speed generation and spending time surfing in the pocket, the 4-A is a fin that will hold then release when the time is right.
