Nothing can compare to the effortless speed and performance of the Egg-O and Kazuma's signature triple barrel concave gets up to speed instantly while giving you total freedom and control to break the tail out whenever you want. 
This board is so easy to ride and will make you a better small wave surfer instantly. Negatives? It gets hyper sensitive on large, fast waves so you better be quick.
