How about Glaramara - Allen Crags - Angle Tarn - Rossett Pike (for the view down Langdale) - Stake Pass and down to Langstrath.
Seathwaite - Ruddy Gill - Esk Hause - Great End - Scafell Pike - corridor route to Styhead and Seathwaite.
Seathwaite - Sour Milk Gill - Green Gable - Great Gable - Styhead - Sprinkling Tarn - Ruddy Gill down to Seathwaite.
As OB says plenty choice - Dalehead High Spy etc to Catbells and down to Keswick and pick up bus back down Borrowdale.
Depends on how much you want to do each day - remember it will be getting dark form about 4.30 pm so take a torch!
