I post here a reveiw of the 7S Superfish XL. Ridden as a 5 fin (quad set up and a small keel type stabiliser fin in the back). Previous reveiws indicated the board to be a bit skatey as a quad, the stabiliser fin helps the the performance while not taking away from the speed with a quad set up! All considered a fun ride, easy to paddle, great for trimming even nose riding!
