The medium flex provides a balance between stability and responsiveness. It offers enough stiffness to hold a line through turns, but gives you a noticeable 'spring' or whip as you exit, which helps generate speed in softer sections.

Not at all. While the extra width at the tip is specifically designed to provide more lift and control for nose riding, the overall raked-back profile ensures the fin remains fluid and efficient through turns without feeling sluggish.

Yes, the matte finish is functional. It helps reduce surface friction compared to a high-gloss finish, which can slightly improve water flow and performance, while also being more forgiving when it comes to hiding minor scratches from regular use.

A good rule of thumb is to match the fin size to your board length: 9.0 inches for boards around 9'0", 9.5 inches for 9'4" to 9'6", and 10.0 inches for boards 9'8" and up. If you prefer a looser feel, you can size down slightly, or size up if you want maximum hold.
