Powerbox used by Exocet, JP, etc
All of the other major Freestyle Wave manufacturers offer these boards with Powerbox fins, Starboard is making a major mistake by sticking with the US box.
It shows they are not serious about the Freestyle Wave market. How many riders will give up their collection of four or more fins when they buy a new board?
Tuttle is perfect for large boards, and it would be my preference for all boards, but Powerbox works well for Freestyle Wave boards, and most sailors I know do not like the old surfboard style fins.
