When a shape is first developed, it is tested by both team and the general public.  Input is taken and one question is always, "How did it float?"  We then develop an appropriate size scale to present to the consumer.

You are trying to mix Cruisers with Classics with High Performance shapes.  Each category has its own style of boards and they generally fall into these flotation standards, although they still may vary from shape to shape within a specific category.
