Firewire Groove 5'10" SurfboardDimensions : 5'10 x 20 1 8 x 2 1 2 x 34L The Grooves rocker and tail template bring this shape back into the world of being able to come square off the bottom and go square off the lip, what everyone calls high performance surfing,' Firewire continued. Rob added in more rocker than his typical shapes, with a tail rocker that puts you tight in the pocket and elevated nose rocker to help you come down tight off the lip without catching your nose.
