"A Twinnie? Nobody rides a Twinnie anymore!" Alex Rogers could not have been anymore incorrect. The twin fin is one of many retro boards making a comeback and we are doing our part to help the cause. With a flat rocker and vee bottom, these boards are fast. The harder rails hold a constant edge easing these boards through any section. The "Twinnie" is offered with FCS and Future fin systems, but we recommend glass on fins.
