Julian's thruster set features a neutral side fin template with a smaller centre fin. This makes it ideal for performing short arc turns, and fast futuristic surfing on and above the lip.
My set comes with a smaller fin in the back, i find this helps me release off the top a lot easier. Hollow steep waves, punchy beach breaks.
Performance boards with shallow concave and moderate-to-low rocker. Please Note: this fin is designed to be used exclusively with the FCS II Fin System, and will not fit in the traditional FCS Dual Plug System.
