In reply to Southern Man:
I'm a big fan of HVS-E2 in the Lakes, but conditions will of course dictate what you can climb.
In the freak event of a heatwave, head straight up to Scafell. Nothing in England compares to Scafell, it is absolutely majestic.
Central Buttress is one of the best mountain routes I have ever done. So is Saxon, but it is one of the hardest (and the crux is almost permanently wet - it felt like 6a to me). The East Buttress is covered in amazing routes, I've only done a couple including the classic Ichabod, which is superb.
For reliability, Gimmer is where it's at. Not so high as other mountain crags and in the sun. Kipling Groove is worth the hype (best though for someone whose top grade is HVS), Whits End Direct is one of the best E1 pitches anywhere, Springbank is good, Equus superb.
Pavey is a wonderful crag, although it looks a little bit like a heap of vegetated choss until you're on the routes. All the classics are brilliant, particularly Arcturus, Golden Slipper, Aardvark (very tough at the grade, but what a pitch), Astra (an amazing middle pitch).
The south side of Gable is good (check out the tough E2/3s on Kern Knotts), but not up to the above IMO, and Napes Needle looks to me like a massive waste of time. Oh yeah, history. If that's your bag, OK...
Dow Crag also excellent (Eliminate A is worth the hype). Esk Buttres is stunning - Central Pillar is a beautiful soft E2 with great climbing in a magical position and location.
Personally, with the exception of Reecastle Crag and Black Crag (Wrynose) I haven't much enjoyed Lakes roadside/single pitch cragging. But others like it. If you're looking for a poor man's Tremadog, you'll find a few contenders in the Lakes.
