In reply to GrahamD:
I think Raven is pretty good at Severe generally. Not novice routes exactly but I don't think the OP was asking for that. As someone said, the routes on the LHS (Evening Wall/Original Route etc) are pretty good if slightly intimidating due to belays and slightly unusual gear placements. Centipede probably similar tho can't recall that much about it. Wouldn't want to fall down any of those gulleys and of course there have been some unfortunate fatalities with falls on the descent from the main crag.
Other than those mentioned, I'm struggling to come up with interesting but well protected severes in the Lakes. I always founds the Lakes routes to be a little more tricky to protect than their Welsh equivalents. It's just the rock type really. South Crag of Castle Rock is charming and sunny but the easier routes are not well protected imho eg. Wall Climb/Slab Climb.
Something like Thomas (?) at Wallowbarrow?
And if the OP hasn't been to Shepherds then def Little Chamonix (stiff V Diff).
