B5 is a superb grade in the peak for loads of ultra classic problems.
Your hitlist should include:
Lurcher Direct, Bell Hagg (1 hard move)
Banana Finger Direct, Burbage North (is a bit reachy, but most shortarses find a way)
21st Century Fox, Fox Hagg
High Traverse, Clifftop Boulder
NTBTA, Stanage
Enthusiast (arete left of Niccotine Stain), Burbage North
Pock Man without the chips, Burbage South (quite tough)
The little arete back and left of Hampers Hang buttress, Stanage (brill)
Solitude, Burbage North
Think Tank, Wimberry
The Little B5 stepped arete, Burbage Bridge
Pebble arete LHS, Stanage
Strawberries, Curbar (can feel nails)
That should keep you going for a while, quite a good range of styles there. When you've done all them you'l have some mad skillz under your belt!
I'll post any more when i think of them....
