Futures Fins Tomo Quad Surfboard Fins 4 fin set The Tomo Quad set is a very unique addition to the Futures line. The template was designed by Daniel ‘Tomo’ Thomson for the El Tomo Fish model by Firewire. The fins generate speed easily due to their large surface area, but the narrower base still allows the fins to pivot in a tight turning radius. Riders can expect to feel loose and springy without sacrificing drive thanks to the forward placement. When paired with the El Tomo Fish the synergy is unbelievable..
