Here is a short review. Condition: Of the tail end of a NW swell. The Bowl, Hanalei Bay. Wave Height:5-6 feet, occasional overhead set. FCS rep told me they made this system with 2 goals in mind: 1) To reduce the amount of time it takes people to screw their fins in. 2) To simplify the fin "buying" process. Essentially, FCS is now going to offer "4" varieties of these fins: carver, acceleration, stability, and something else. You buy the fin that fins in that range. I tried the carver variety and it sucked. I like a particular fin, with a particular material, and with this system, that goes out of the way. I primarily surf on the R-2, MF-1, PG-7C, or G-AM. All are stiffer with a larger base. The rake vary. This system throws fins for fins that fit in the four categories above. So its not like a can pick a stability fin made of carbon right now. Also, no compatibility between both systems. anyway, YEA, its easy to pop the fins in. But how freaking long does it take to screw fins in anyway? its not like I am saving one hour. The fin is pretty solid in the slot. But what happens if I hit reef? The fin will pop out, plain and simple. Also, on anything bigger, the fin does move a bit. That made me nervous. I will stick to my screw fins for now, as most local people hated it.
