@LA: VFR-Night is not allowed where I live now, so my experience may be outdated, but from the time flying night in Europe I remember quite many occasions, where the controller gave a !!!! on what I filed. They usual case was picking up knowing my destination and then route me where they think it may fit - I don't remember any night flight flown as filed. During night routine they always treated me flying NVFR exactly same as any other IFR flight, so my past experience is that NVFR is better told dark IFR-light.
