it is a stringent list for an area that IMO specialises in crags with a few outstanding problems and a few warm ups in stunning locations on great rock. Eg Gillercombe has a couple of great 7’s in an amazing setting, but not a huge lot else. Actually combining Gillercombe and Sour Milk would give you some good 7’s to go at.
None of the low 7’s at Kentmere are particularly classic, The Hole and the Weasel ones are quite good, not tried the Badger Stone ones.
