The heel side of this board is the bump. Our revolutionary twin tip considered by many including Trip Foreman, owner of Real Kiteboarding to be the best twin tip ever made. The toe side is the Trow directional. It is hands down the top board for wave riding. This board gives you the best of both worlds. No need to jibe. Super smooth ride, awesome pop, and the carving power of a Trow directional. Rocker Flat in the center, with curves accelerating towards each tip. This is the rocker we have used since 1999. A proven formula. Rails Double edge surf rail. Bottom Single concave, which is shaped in from rail to rail. This helps to initiate edging easier and with more power. We fade the concave out in the tips to give the board more pop. Fins 3x4 Price 699.00
