I used this fin on a regular surfboard and noticed a significant improvement in high-speed performance. The ride feels more fluid and responsive, especially when carving turns. It’s a great fit for boards that aren’t half shapes.

The fin works well with my longboard. It gives a smoother ride and feels lighter than the standard fins I’ve tried. A bit more expensive than expected, but the performance is worth it.

As a beginner, I was skeptical about trying a narrow base fin. After a few sessions, I found it much easier to maintain balance and control at speed. Definitely recommended for intermediate to advanced riders.
