In reply to lynchit:
Though I rate Pex Hill very highly, for leading at S-VS it's not a good option. Most of the Lancashire quarries are green and cold in the winter months, but Anglezarke has some areas that that catch the sun and it has lots of easier climbs. Some of the VSs there (like, say, Metamophosis) may seem a bit harshly graded if there's been sand dribbling on to the holds, which there usually has after rain.
Helsby is another possibility but only gets sun later in the day.
