Thanks for the advise on the FCS fins. Another question, please. Can sI get an explanation about the difference between the composite, carbon and fiberglass FCS fins? We would I choose one over the other? Does it make much of a difference?

Composite fins are typically glass filled nylon or sometimes glass filled polycarbonated. They are molded and consequently very consistant fin to fin and less labor intensive to make. I’m currently making a new NACA foil generated Next Generation of Red X fins from a much stiffer composite material that should be a big step forward for composite fins.
Fiberglass laminated fins are stiff, durable and very labor intensive. Meaning their shape is dependent upon the craftsman making them.
There are two types of carbon fins. Composite fins with a carbon filler as apposed to glass. The second is RTM cored fins. These are very light, molded fins that are expensive and fragile. But, they are also very stiff. Currently, my favorite fins in our line are the AirCell Carbon X-2s.
stiffness and price are the big differences…the carbon fins are stiffer and thus more drivier…the basic composites flex quite a bit…flex can affect cant a lot and toein a little…some argue that flex is good because the fin penetrates the water more vertically as you surf…others disagree on those benefits and say stiffer is better.
