The FCS II Britt Merrick Twin Fin set bridges the CI Keel and AM Twin, giving you the drive and hold of a keel with the pivot and release of an upright twin.

As a general guide by surfer weight: L-XL about 165 lb and up. If you're between sizes, size up for more hold or down for a looser feel.
Will these fit my board? They fit boards with FCS II fin boxes. They won't fit original FCS two-tab plugs or Futures boxes.
