Feather Tor, Dartmoor National Park

The cloud was forecast to clear about an hour before sunset as a high pressure system rolled-in.  My hope was that it wouldn't completely clear leaving some nice thin clouds and making for a colourful sunset.  So, after arriving at my accommodation, I sat and considered a plan for the evening.  Should I try Feather Tor, Great Staple Tor or even Great Mis Tor?  They are all open to the West and low-angled evening light.  Was the cloud going to clear sufficiently to make a longer walk-in worthwhile?
