Its a full circle thing, you start out riding whatever the shop sold you when you were a kid...and you keep surfing different boards through the years, never really settiling on one board design or one shaper...
Then you figure out...hey, how fucking hard could it be to shape your own? You know what works for you and defineatly what doesn't.
So there ya go.
Shape it, glass it, ride.
It wont sink, trust me.
