The way GB is building it is really cool.
The cut-outs are made to where the water entrance and exit holes are positioned quite well so that they do not end up slowing the ride or dragging the bottom of the board down. The purpose of the cut-outs is to allow the rider a finless board that still has the edge and hook of a finned board. Think about it, you can still carve hard and break loose whenever you want. I cant wait to try it at the cable parks.
The only problem I see in it is it only comes in a 140........ So I start my diet tomarrow
