The FCS II Mark Richards Twin + Stabiliser Fins pair MR's famous twin template with a small stabilizer that adds control without losing twin fin freedom.

As a general guide by surfer weight: M-L about 145–200 lb. 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.
