( Twin-fin set ) 80/20 Foil: Designed by Tyler Warren, these are some speedy fins made for the modern twin fin shape. The Modern Keels feature a lengthy base and an extended amount of rake that will provide exceptional amounts of drive. These fins are well suited to be used in fast, and down the line type conditions. These fins (which we have always offered as glass-ons) have been specially developed with a slight amount of angled relief in the base in order to fit in Futures fin boxes.
