If your only purpose is fine line detailing, I would agree that the Badger may not be the best airbrush, since it is more of an 'all-around' airbrush. Having said that, I've been able to use mine for panel highlighting and shading with no issues at all. It will do fine lines with no problem at all, provided your paint is thinned properly, you are using very low air pressure, and a light touch on the trigger.
