The Machado PG Quad Rear/ Side Byte by FCS offer a great mix of speed, control, flow and responsiveness. This is Rob's go to fin for the Firewire Seaside model. Designed to provide the connected feel of a quad fin setup with the drive and speed typically generated from a keel twin fin setup. These will also function as side bytes in combination with your Single Fin. Works great in smaller beach break waves and nicely lined up point breaks.
