Product Overview
Our original fin for performance wave riding. Lots of flex for amazing grip and looseness on the wave. Raked template for control. A progressive foil for different flows between tip and base. Test winner. Will loosen up a 'stiff' board and are particularly sweet as twin fins as they eliminate that unwanted top turn spin out.
Flex: HIGH
Sizes 12-17cm US SLOT heads.

These sizes will actually be similar to the sizes you would use in G10 but feel looser, lighter, grippier, more controlled with more drive and hold through the turns, at the expense of some low end early planing power. You'll also notice the flex will sling-shot you out of your turns and provide grip at extreme angles where stiffer fins would leave you bum checking as the tail slips away.
Please note that wider boards and/or heavier/taller and/or less skilled riders will require longer fins than those shown in the table and vice versa.
In really windy choppy weather, you may also choice bigger fins to make the board more 'planted'.
