Watch Kani surf and you will see what this fin is all about. Its solid base gives plenty of hold in the pocket when hanging ten and delivers speed and drive throughout turns. This fin delivers it all with sustained nose rides as well as the ability to put the board on rail without sliding out or losing speed. The tip has just enough flex to provide that extra burst of speed coming out of maneuvers to connect turns and beat sections. This fin works great on mid-lengths, too.
