FCS M series are fast and smooth, with better hold and more squirt through turns.  The M-series has a flexible tip for forgiveness and control at high speed.  New Inside Foil Technology offers superior drive and hold.  

What even FCS can't have fully expected is the reaction to this fin from surfers - even pro riders with unlimited budgets are riding this fin for the performance it offers.
