Alpha Reverse 3/2 Twin + 1 Deck Grip Single Tab variants are compatibleThe Alpha Reverse 3 2 Twin + 1 is designed to surf your favorite twin board at full throttle. The Reverse 3 2 refers to the twist in the foil, through the top third of the fin, that adds an additional 3 degrees of cant and 2 degrees less toe. The Reverse aspect is that the toe angle straightens only in the tip. This creates two separate foil surfaces, one at the base of the fin and one at the tip, that both feature Futures proprietary Vector foil.
