The FCS II Christenson Keel Twin fin PG X Large fin set from the FCS Shaper Series. This cracking keel set is designed with plenty of curve in the leading and trailing edge to provide smooth rail to rail transitions. A thicker flat foil gives this set up more grip and drive through turns on bigger open face waves. This Christenson Keel set up gives you all the speed you'd expect but more control and an overall smoother surf. Its suited to any twin fin set up, preferably boards with a wider, thicker tail area.

The Performance Glass (PG) fins are machine cut from layers of solid fiberglass. These fins are stiff, and are widely used by pro level surfers because the integrity of the flex is maintained under immense force, and in the most extreme of conditions and situations. Don't be too scared by this description, some of the kooks here at Boardshop have used them and they do actually work well!
Give them a try! Several team riders have put these twins through their paces and loved them.
PLEASE NOTE: These FCS II fins are NOT compatible with the original FCS and FCS Fusion fin plugs.
