The goal of this fin is to not only be an extremely versatile "all-rounder" but also to truly excel as both a trimmer and noserider. With a profile that's inspired by Greenough's "Stage 3" design introduced in the late 60's, the upright stance coupled with the extreme leading-edge foil both act to release water more quickly than a 4A, but the wide base has more drive and control than a Frye flex or Greenough 4C.
