What a dilemma! Well here is the scoop. It is all preference, really! its what you want. We use the FCS fusion fin system standard on our boards because the FCS fusion box allows us to install the fins easier then the old system. It is stronger and cleaner than the old X-2 system. Now Futures, this system is very similar to the FCS fusion and has been around longer, the box is larger than the fusion and has been found to flex less. Both systems are installed directly into the foam before glassing. The difference performance wise for these fin systems are flex. The FCS fusion system allows for slightly more flex and energy transfer into the board its self then the futures do, this said the futures are not far behind and to be honest choosing one or the other won’t make you the next Kelly or Dane. Its all preference, if you have plenty of future fins lying around then use futures. If you have FCS then use FCS. All our boards come standard with the FCS fusion system and fins unless you specify otherwise.
