Channel Islands Twin Fin Set FCS SIZE:EXTRA LARGE Avoid Regret"( 2 Fin Set ) FCS Compatible, Flat Inside Foil: This is the original template for the CI twin fin dating back to the early 1980s. It is a looser twin as compared to the Mark Richards style twin, and when hooked up with a small trailing center fin, makes a great loose feeling thruster. You will feel the speed of a twin fin along with positive drive of a tri fin." True Ames
