Seen some discussion on FB in the last day or two saying the track is not drivable unless you're in a good 4x4. Not been past myself but Rushop Edge has been pretty bad for snow and sections of the roads around there have opened and closed a few times in the last couple of days. All roads are open now, but the track stays bad for a while longer. The thaw is coming so I guess it depends on how soon you plan on going. Sorry I can't give a more definitive answer and hopefully someone else goes past today and can tell you exactly what it's like.
