Pretty much any south-facing valley crag will come into condition quickly. So, Langdale or Wallowbarrow are great. I spent a lovely day at Wallowbarrow on the 13th of Feb last year, when the wind was howling from the north; belays were spent loafing in calm pools of sunlight, but when you topped out you suddenly saw the fells covered in snow and felt the bitter wind buffeting your ears and chilling your bones.
If it's dry for a sustained period, as it was a couple of weeks ago, then more places become doable. Eastern-facing means it'll get the morning light, to aid drying. Wind helps with drying, but can be cold!
Shepherds dries very quickly, and if you're going to go there at all, it's better to go very early in the season, when you'll only see a handful of teams, rather than people on every route. The good thing about Borrowdale (and Langdale) is that you can check out one crag and, if it's taking drainage or whatever, easily and quickly head to another - e.g. Lower Falcon, Shepherds, Black Crag and Quayfoot can all be checked out with minimal time spent walking in.
Black Crag and Long Scar are great unless there's a wind blowing, in which case they can become bitterly cold, depending on the wind direction. However, they have different aspects (W and S), so sometimes Long Scar is bitter (N or NW wind), but Black Crag is calm and sunny.
Silverdale's quite good for early season, too - Trowbarrow dries reasonably quickly and is sheltered from the wind, whilst Warton has small crags facing SE and SW, so you can make the most of the sun.
After a while, I get sick of going to the same valley crags, though, and take a punt on something higher up the hills!
