In the Peak you have Beeston and High tor, both of which are very pockety from my experience, even more so round the bend from High Tor at the less well known Pic Tor. All these are trad, though I assume some of the retrobolted routes on the right wing of High Tor and the sport routes through the Beeston bulge must be of the same ilk.
For pocket orientated sport I only really know the route Beginners wall down Blackwell Dale. I'm a fan of pockets so I await better answers eagerly.
