The AM-2 is designed for performance-oriented boards featuring deep concaves and moderate-to-extreme rocker. It is best suited for boards that need extra drive and hold in critical, hollow sections.

Yes, this is a five-fin set. You can configure it as a thruster for more traditional, pivot-oriented surfing or as a quad for increased speed and hold in down-the-line conditions.

The smaller center fin is specifically designed to reduce drag and allow for a quicker, more responsive release during turns. This makes it easier to break the tail loose when you are performing high-speed maneuvers.

No, these are FCS II fins. They are designed for the FCS II tool-less system, which allows you to click the fins in and out without needing screws or a key.

While they can work in various conditions, they are engineered primarily for hollow, steep waves and punchy beach breaks. If you are surfing very small, weak waves, you might find a fin with more area and upright geometry provides better lift.
