The flex pattern in PC fins extends progressively from the base through to the tip, helping the surfer to maintain drive and hold through a turn. This versatile fin material is light, and can be used in a variety of different conditions.

Not a good fit for my HI4
I got these for my 9'1" HI4 when I use as a quad. Compared to the 2+1 setup I use they make the board feel sluggish and harder to turn, and not near as stable when noseriding.
Don't know if they are too big or too foiled or what, but I figured they would work better tha they do given they are supposedly designed to be paired with my board.
