Vg's havs a local air flow directional dependency(can be as much as90 difference from 1 to the next)tuft testing is needed for proper application. VG will allow steeper change of angle with out loosing attached flow. Consider a 3D Printer to produce in house. (I see a short ROIwith the volume of VG'S needed as well as the capability to produce scale models for testing)
