My first twin fin was by Bob Stassi. It was a round pin. It was a real good board. I haven't seen many over the years. I made a stock one and put it in Central Coast Surfboards, CCS, Awhile ago. Recently James called me and told me he rode and loved his friends board that I made. It was the board out of CCS. He ordered a custom and here it is. 6'2''.
