I am currently using a low density EPS (styrofoam) board without nozzle, with a more angled tail and support for five keels. I confess that I surprised the design in the beginning, but in the water I was surprised by a lighter, sturdy construction with a hydrodynamics that provides more speed and fluidity in the maneuvers. A great choice when it is necessary to use more of the edges of the board and break a little more movement, a condition that usually meets in seas with small waves.
