Aloha! I've been surfing the past few days. The fin you recommended is perfect! First thing I noticed was how smooth and fast it was. It felt like I was flying across the water. When set in the middle of the fin box, and even a bit towards the tail, the tail still skipped when pushing hard of the bottom. With the Finjak, I eventually moved the fin all the way forward and voilà! Everything clicked into place. The next waves the Pinder board almost felt like a thruster. Mahalo guys!

Why You'll love this fin!
- The 4A is perfect in so many ways. It checks all of the performance boxes. The solid-sized base and width create stability and drive, while the rake and flexible tip enable top-to-bottom turns and maneuverability.
- The Greenough 4A is a bread-and-butter fin. It allows you to feel the shape of a surfboard, it never gets in the way, with it's perfectly neutral design, when sized correctly to the board it fades away and becomes one with your surfing. It holds you tight but lets you loose, and it gives you feedback but disappears- truly the most versatile fin on earth.
- The true beauty of this fin is that you can ride it in any board that has a single fin box. The larger sizes (9"-10.5") are great for single fin longboards, the medium sizes (7.5"- 9") pair well with speed shapes and mid-lengths, and the smaller sizes (6.5"- 8.5") pair well with shortboard single fins and 2+1’s (boards with side fins).

Been giving 9” Miss Lucy a chance on 9’6” Brewer log, but never felt good. Finally decided to switch to the 9” Greenough, and the difference is awesome. Way more freedom on turning and takeoff. Still holds on nose rides. Like my board is brand new to me again!
