we tweaked the standard FX-2 by adding a round tail and a narrower nose.The tail gives greater edge control and tighter turning arc while the slightly reduced nose area allows for a more vertical approach to the waves.Super fun and easy to ride for waves from 1-4 feet or a bit bigger for those that like to push a design to the max! Comes standard with 5 fin plugs so you can ride as a quad or thruster.
