Can't decide whether you want a thruster or a quad? Why not have both. Many boards now come with 5 fin boxes, so that you can pick and choose if you'd like your board to be a thruster or quad, depding on how you like it, or how the surf conditions are. 5 Fin sets allow you to feel the differences between Thruster and Quad without worrying that its the fin template making the difference.
