Don't be afraid to get yourself up to the popular end of Stanage and enjoy yourself. Ignore those who moan about it always being busy and full of newbies - you're just as entitled to go there and climb as anyone else and if they are annoyed then they will have hundreds of other routes to choose from!
Birchen Edge is always a reasonable alternative, though the starts are notoriously awkward.
Burbage North has some nice routes but not in great numbers.
Quarries such as Yarncliffe and Lawrencefield have little gems but as you said there's not great volumes.
Enjoy Dave.
