One of my Dave Parmenter fishes originally came with FCS triple plug keel fins. I’ve never seen keel fins on modern/hybrid fishes before so when I saw the fins on my fish I was somewhat skeptical. I’ve heard a few shapers say that keel fins are needed for retro fishes with wide tails. That being said, the FCS keel fins looked like a bit too much fin for my narrow tailed 5’9 fish. Another note worth mentioning is that the FCS keel fins are quite heavy and made my fish feel extremely tail heavy. I’m not exactly sure if that has any negative effects on performance but I think that lighter fins work better.

These fins weren’t working very well and the board was totally unresponsive without any speed. It was basically a dead duck in the water and a total dud! I decided to replace the heavy keel fins with the FCS MR Twin fins iand all of a sudden, the board had life again. The MR Twin fins created a unique blend of drive and looseness inn the turns which made this board a terror in smaller surf. The MR’s trailer fin (included in the MR twin set) created more drive in the Parmenter fish in larger surf. The MR fin with trailer is a very versatile system which allows you to change the dynamics of your board for a variety of conditions.
