This fin is the evolution of the first SL 2007 model, After testing different profiles with Micah Buzianis we made this model faster then the previous one with keeping the early planning characteristics, A lot of PWA racers switched to MFC last season, proving the high performance of this model, Good for lighter people and a little flatter water, Ideal for Slalom condition, it can be also used on freeride boards,,, to go faster!
