I'm big fan of rockers,so much so I took the Fireball Evo square tail rocker and put it on a UFO outline which is prefect for the points,easer paddler,more surface on the water works a treat,more speed, verse the UFO 3 stage rocker which is suited better to beach breaks imo.
I've used the Fireball Evo square tail rocker on anther board which also works a treat.
