In reply to jonathan shepherd:
5+6 and 7+8 are the clearest guidebooks in my opinion (of course that's assuming you operate at those grades). Not quite comprehensive because they don't include traverses, but the majority of traverses are ugly and boring anyway. Contrary to other guidebooks they're presented in landscape orientation, which makes more sense than portrait orientation since many areas follow east/west ridgelines. Directions are spot on.

Er... Having climbed polished yellow and orange slabs just last week, this is an exaggeration. You can add a + , but I've yet to find an f3 slab that feels as hard as, say, La science-friction (the mauve circuit is a massive sandbag though, but it's also no longer maintained now that many problems are fenced off or lichened, such as the Dame Jouanne itself. However you have to make the distinction between "alpine" and "modern" circuits, the former being indeed harder than the latter even when the colour is the same).
(And polish on those f3 slabs has little to do with pof if you ask me, and much more to do with the sheer numbers of climbers and dirty shoes to a lesser extent.)
PS: glad to know I'll solo E1 when I travel to the UK
What can I solo if I've done Le mur de la mort, E3?
