I saw these today when I was messing around online and I figured I would let everyone know about them, I know alot of people tend to gravitate towards Sweet Potato's with Futures boxes due to the great feedback about the controller quad set and how well they complement the board.
It appears that FCS itself has come out with an extra large Quad set designed for Wide tailed hybrids which could potentially be the ticket for the SP.
They are huge fins and they also look really great to add on top so who knows, maybe they will one up the controllers and take the SP to new places, don't own an SP myself but maybe one day and if that day comes it sure is good to know that if it has FCS boxes I don't need to contact some guy in Indo to make me some "indo fins". I can just walk down the street and buy conventional fins with state of the art materials that will probably do the trick.
Cheers and let me know how they go if anyone decides to try a pair out, or if they already have and were just hiding trying to not let the secret out.
