This lighter, stiffer and more performance-focused construction maintains strength through the base and central spine while preserving controlled flex through the tapered tip. Designed to complement the Driver’s elongated template, it delivers strong drive and stability through powerful turns, with fast rebound and a highly responsive feel under load. Ideal for powerful surfers who demand greater speed, control and response from their fins.
