The new Quad 5"11 has a touch more tail rocker than the Classic 5"11 Thruster. Ross tuned the new quad to be more of a true surf style wave riding machine, while the Classic Thruster remains a great all around shape waves, chop, flat water.
All the 2012 Quad boards feature bamboo veneer top and bottom.
I’ve been riding the 2012 proto 5’11 (bamboo) since March and its my still my go to board. The combination epoxy bamboo gives the board a snappy feel while taking the abuse of living in the back of my truck!
