George Greenough has certainly made his mark on all things surfing and here is the best of the best.
The full base coupled with the tapering, moderately flexible tip creates a balance that transcends and complements so many aspects of surfing. Of course a unique understanding of his aquatic fish friends is the foundation here. Install the 4-A on any performance surf vehicle and you will find instant bliss.
We love this fin as a high performance option.
