^What he said.

I'm not a believer in "venting" for the purposes of lower aero in large part because internal ducts- faux or not- have their own drag. I also don't usually subscribe to protruding airfoils and vortex generators and such as being assets either- perhaps they can be made to help a bit after lots and lots of scientific refinement in a tunnel, but I see them as band-aids that aren't even attempting to cure the root of the problem, that being a flaw in the core shape.
