Performance Core
Performance Core (PC) fins are made using a multi-layered resin transfer molding process. 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.
MEDIUM (65Kg - 80Kg / 145 - 175 Lbs)
LARGE (75Kg - 90Kg / 165 - 200 Lbs)

Honestly having used futures and fcs.. fcs has it figured out. The click in system is 1000x more intuitive and effective than futures. I often try new setups mid sesh or swap before next one and don’t need to carry a key or fear stripping the screw.
I haven’t figured these fins out yet but that’s user error and bad board selection.
Nice fins for beach breaks ! Perfect set up with my merrick happy everyday
Tight turns in the pocket. Good start up speed. More up right than original reactor. Great addition to my arsenal of fins.
a little less drag/hold than the Fannings, more springy but still great hold through turns and drive for generating speed
Exactly what I expected and performed as needed
