True Ames Greenough 4-A

This fin is incredibly versatile and pairs well with mid-lengths, longboards, and eggs. Its balanced design makes it a reliable choice for almost any single-fin setup where you want a mix of drive and maneuverability.

The moderate flex allows the fin to load up energy during bottom turns and release it smoothly as you exit, providing a lively, responsive feel. It offers enough stiffness for stability while still providing that springy sensation through arcing turns.

Yes, the full base provides plenty of surface area to hold your line when the wave gets steeper. While it isn't a dedicated high-performance thruster fin, it offers reliable grip and drive that keeps you connected to the wave face.

An 8-inch fin is typically ideal for mid-length boards or smaller logs in the 6'6" to 7'6" range. If you are riding a longer board, you might want to consider sizing up, but for most mid-sized single fins, this depth provides the perfect balance of pivot and drive.

The tapered tip is designed to reduce drag and increase responsiveness. It allows the fin to pivot more easily during turns, making it feel less 'stuck' in the water compared to fins with a wider, fuller tip.
