During early R&D, they tested both the AMK and BMT templates. The AMK delivered impressive down-the-line speed but felt like too much fin in tighter, arcing turns. On the other hand, the BMT lacked enough surface area for drive and stability, so a more refined fin tip might allow for smoother transitions.

Britt refined the AMK pulling back and rounding the tip along with a few other tweaks to fine-tune the outline. The result is a beautifully balanced fin that delivers speed with a dependable sense of control and flow through turns.
