Fin configuration: Four on each end. Two 1.1" aluminum A-Wing fins and two variable-sized molded-in outer fins. Construction: Foam core, layered glass integrated from top to bottom. Company comments: The Eden series is a shape that you don't have to learn how to ride. The features let a boarder determine their style. This series is the building block to the rest of the high-end line. With a softer, ladies-specific flex, the Eden is a great choice for the girl looking to take it to the next level. An asymmetric shape allowing a rider to stand higher up the wake on their toeside edge with increased leverage on their heelside rail. Deeper molded-in toeside fins set a harder cut, shallower molded-in heelside fins create a quicker release. Outer stabilizers create a more stable ride and help a rider recover from off unstable landings. A snappy 3-stage rocker with a full-length "V" bottom tunnel helps break up the water for cushioned landings. Ladies specific "Satin Flex" allows for a slightly softer board flex.
