How it surfs
Team-rider footage from Mendiguren ("Flying diamond x Mendiguren") showcases the board's ability to hold vertical lines in overhead European surf — proof that a twin doesn't have to be a small-wave-only shape.
Buyer feedback from Pukas Surf Shop and Boardcave consistently highlights the same qualities: paddle-easy shortboard, projection through turns, and a much wider wave range than most twin fins.
