(^^) ↓Trivia from the NEST store manager, Japan's number one fin fanatic (tested on about 170 boards)... The template is quite similar to the Machado Keel fin. You can see it if you look at the comparison image with the Machado Keel in image 4, but that part is slightly different. This fin is heavier than the Machado Keel. I think the flex of this fin is also slightly stiffer. Basically, those who have boards that fit the previous Machado Keel should be able to ride it well, but since there are subtle differences, the ride feel may also feel slightly bigger with this fin. Those who have used the Machado Keel this year will know that it is a very good template fin among twin keels. If you have any other questions, such as whether we have stock of fins you can't find on Mercari, or a comparison of the ride feel of this fin with your current fin, please feel free to ask in the comments section. I will answer as much as possible. *Please understand that there may be color differences between the photos and the actual product. *You can purchase it as is. *The fins listed as new and unused are definitely new and unused, but there may be some scratches or print misalignments due to the manufacturing process, so please refrain from purchasing if you are sensitive to such things. *We generally do not accept price negotiations. m(_ _)m If you have any other questions, please ask in the comments section. Thank you for viewing. (^^) Type: Fin Fin System/Fin Box: FCS2 Number of Fins: Twin Fin
