Fangy Fin 28. Use it with 85 wide and 8.6 or cut it shorter to suit your needs as we have done.
Coming soon for those looking to go fast rather than bolt a metal anchor to their boards, the designed for speed Carbon Delta XT-50 with is thinner profile for speed and carbon construction for lightness and stiffness.
The fin setup on that board looks great just need 3 Delta XT-50's so you can get into even shallower water!
That looks great....loads of grip.
