In reply to Anhibian:
Couple of route suggestions, both starting at wasdale head:
1. Go up styhead pass to the stretcher box, or if its dry enough scramble up spouthead gill (grade 3 if you take all the difficulties). Then head along the climbers traverse to the napes. Thread the needle (mod) and head up one of the ridges, I'd suggest arrowhead ridge (diff if you take the easy start, vdiff going direct). Descend sphinx ridge (grade 2) and do another ridge on the napes, I'd go for eagles nest or needle ridge (both vdiff). Then continue to the top via Westmorland crags (generally given grade 3 but you can make it harder if you want). Descend whichever way takes your fancy.
2. Go to pikes crag on scafell pike, either direct via the tourist path up lingmell gill or better via styhead pass and the corridor route for more time on legs. Climb crenation ridge (diff) and take the abseil descent. Head over to mickledoor the along rakes progress under the scafell crags. Climb slingsby's chimney (vdiff). Abseil off high man into the jordan gap and scramble out onto Symonds knot. Descend via lords rake, nipping up Castor (mod) on the way past.
Do that in one weekend and you'll probably be ok. You'll need a partner to rope up for the harder bits unless you're very comfortable soloing vdiff. It will be good practice to switch between soloing/moving together/pitching too. The exposure on some of those routes can be pretty intimidating, plus slingsby's chimney can stop people in their tracks if not accustomed to traditional thrutching.
You can make loads of variations on the above. The cicerone scrambles in the lake district north and south books give loads of link ups with options to vary the difficulty level.
E2A! Just looked at your profile, apologies you probably don't need advice from me on whether to rope up or not for any of the above
