The FCS II Performer Twin + 1 Fin Set sits between a twin and a thruster. Think of it as about two-thirds twin and one-third thruster: the smaller side fins give you speed and a loose tail, and the oversized stabilizer adds the control you need to hold a line when you push hard.
| Fin system | FCS II |
| Setup | Twin + stabilizer (3 fins) |
| Construction | Performance Glass |
| Sizes | S-M, M-L |
| Colors | Cali Blue, White, Blush, Black |
As a general guide by surfer weight: S-M about 120–175 lb; M-L about 145–200 lb. If you're between sizes, size up for more hold or down for a looser feel.
Will these fit my board? They fit boards with FCS II fin boxes. They won't fit original FCS two-tab plugs or Futures boxes.
Can I ride it as a straight twin? Yes. Leave the stabilizer out for a looser, skatier twin feel, or put it in when the surf gets bigger or you want more hold.
