Matt 'Mayhem' Biolos's specialty quad fin set. High area quad keel set adds bite and control to hybrid boards with wide tails, without sacrificing pivoting capabilities.
Open face, down-the-line waves, particularly good in point and reef breaks.
Modern fish and hybrid models with moderate-to-low rocker.
Please Note: this fin is designed to be used exclusively with the FCS II Fin System, and will not fit in the traditional FCS Dual Plug System
