In reply to Nick Smith - UKC:
Great North Road - probably the best, sustained brilliance. (Great Portland Street felt very disjointed by comparison).
Right Unconquerable - almost over too quickly, though I guess that's the point: the lengthy psyche-up... then the sprint.
Congo Corner - after the initial crack is rather pleasant.
Saul's Crack and Mantis, Roaches - a contrasting twosome, I found the former desperately thrutchy, the latter whilst not classic is a really pleasant micro-route.
Demon Wall and Great Western (RH finish), Almscliff - good climbing with DW always having a proper sense of forboding for me (until I did it) due to the number of failed / desperate onsights it seems to attract.
Angel Wall, Caley - top microroute with great thank-f**k jugs
Mind you, I would probably rate my two favourite single pitch HVS's (aside from Great North Road maybe) as being in "the county": Main Wall at Great Wanney (5b and just keeps coming with at least 3 "cruxes") and Crystal at Crag Lough (long and interesting with an almost "mountain feel").
