I just delivered new quad sets to Mitch's Surf Shop in Solana Beach. Below, center are AK-4's. L and R are (2) sets in a template that I did for Thomas Campbell and Danny Hess a couple years ago. Both called it a "magic" fin set.
More Marine Ply: Mitch's also has some great twin keel sets available. In a few days they will also have some popular "D" templates for longboards and Nuueva noserider glass-on single fins available.
