Excellent condition, the strongest for competitions, AM1 same template, Captain Fin M Dane model This Dane model is the same template as AM1. I've included a photo of it overlaid with an AM1 fin. (15-20. AM fins are for comparison only and are not the product.) AM fins are recommended by many pros on YouTube. Here are some YouTube videos: Pro Yasui, Pro Noro [Surfing] If you're unsure about fins, choose these!!! Fins highly praised by top pros! Pro Kawamura [Surfing Changes] Fin settings used by pro surfers [with surfing footage] Pro Murata [New FCS Fins] Pros actually compare riding three fins! Which fin will the pros choose as the strongest!? Pro Kawahata [Surfing Transformation] We discussed how to choose fins and the importance of them with Dol-kun. Hideyoshi Tanaka, Masatoshi Ohno, Keijiro Nishi, and past Grand Champions often use AM fins in their videos, and top pros from around the world such as Leo Inaba, Kanoa Igarashi, and Connor O'Leary also use them in competitions. Recently, Shun Murakami and Hiroto Ohara also used them at the Shonan Open. Both of them performed incredible actions in onshore small waves. They are truly the strongest fins. Explanation from FCS: [Industry insiders talk] FCS fin selection explained! An important choice that dramatically improves the performance of surfing and surfboards! Why they are suitable for competitions: [Chiba VS Shonan] The surfing dojo match between young Shonan surfers VS top pros from Chiba was too exciting. There are other models with smaller center fins, but the AM has a laid-back shape, and the small center fin combines drive and excellent release.
