YU techflex
The YU Techflex is a rakey fin designed by Japanese shaper Yoshinori Ueda for high-performance surfing in punchy waves. The Techflex material provides a responsive flex pattern for speed control in powerful conditions. The YU has a wide base for drive off of the bottom, lots of rake to provide hold through carves and a really refined tip for the right amount of release.

FLAT Foil
Flat foiled fins break free sooner, and are better at controlling speed. Often surfers prefer them in fast powerful surf where they do not need to create additional speed. If you have muscle memory from riding glass-ons, flat foiled fins will feel the closest.
