DORSALSurfboard Fins Quad 4 Set FCS Compatible Green Carbon Fiber with Honeycomb Hexcore

I haven't ridden these yet, but the reason for the initial 3 stars is, Not the same color as depicted. AndThey are not a "Traditional Set" in that the rear fins have an 80/20 foil, which I don't mind that much, except that I ordered another set of fins form the same company that are 80/20 foils, so now I have identical sets (except for one is carbon). Also, for the extra price of this fin, I'm not convinced the Carbon will make for much of a difference. More of a placebo than anything, I expect. Still, for the money, they are probably just as good as the FCS costing much more, so not a bad purchase.The rear edge of these fins is on the dull side, which, if it works, just fine with Me - safer; so better (if no hums etc.)No perceptible weight difference that I can tell, but I didn't weight them.The Carbon is a bit less flexy than the non carbon.No problem fitting into the FCS plugs.The Included Key seems to have a nice touch, in that the shaft curves inward where it's embeded so that it shouldn't be able to strip and turn. Not sure if they all do that, but this one in clear, so you can see it.Fins come with a cheap Plastic carrying case to keep the fins together.I really should be giving this more stars, so stay tuned and I will update once I try them.Like I said, the fins seem great; it's just the lack of info on the foil that bothers Me.

Works pretty well. Only tried it once
