Not a review, or a question, but a comment: dimpling does NOT promote laminar air flow. Dimpling produces a turbulent boundary layer (the opposite of laminar), which mixes higher-energy airflow nearer to the surface of the helmet, thereby allowing flow to stay attached through larger flow angle changes, such as those around the back of a helmet or a golf ball. That's how dimpling reduces drag.
