FCS II Pyzel Thruster FinsJon Pyzel's "JP" shaper fin. Designed as an All Round template, the JP is defined by its Lock, Load and Explode characteristics. The longer base and narrow, tapered tip injects some critical elements for surfers who like to drive hard off the bottom and get the fins free off the lip. Like a typical All Round fin, the JP feels reliable in different waves and boards. It's fast and loose with an underlying feeling of control, thats not overbearing.
