Hi Caleb
Wynd Cliff main crag is just as good a sun trap as Wyndcliff Quarry if you plan it right. Don't go to the area round Questor - that's heavily shaded by yew trees. Go to the Left Hand Crag in the morning and start on anything from Papillon rightwards - Sinew is possibly the perfect winter suntrap route. Then in the afternoon go to the far right-hand end of the Right Hand crag - Klute and Shaft will be basking in the sun. The whole crag is pretty sheltered from the wind.
Shorn Cliff isn't great in winter - doesn't get any sun until after 1, and then it only slants across the crag. Goblin Combe is very good, but in mid-winter skip Owl Rock (the sun doesn't get high enough to get to the bottom of the crag) and go for the higher crags - the Arkenstone especially is a great sun trap.
When the leaves are fully off the trees then Dennis Grove (Symonds Yat guide) is a lovely spot - faces SW, and in the trees but they're mostly deciduous so plenty of sun gets through in winter.
Further afield I would have thought Tirpentwys would be good (not been in Winter, but it's SW facing and in a sheltered valley) and Chudleigh is a surprisingly quick drive from Bristol and I would have thought is good in winter - again, I've not tried.
