Soft doesn't mean they should be the next grade down.
I thought Dark Art and Black Crow fine at soft 8a and soft 7c+. Might be being a bit shorter than the average climber. Soft doesn't mean they should be the next grade down.
Fine Art 7a
One thing to remember is that yes, anston grades do seem soft compared to peak limestone, but is this not because peak lime grades are ridiculously hard compared to just about anywhere else in the country? With a few obvious exceptions.
Do you need Pleasley grade opinions? I've been there quite a lot more.
Yes Pleasley will be in and the newer spots close by. I'd be interested to know your opinions. Some of the climbs here have changed a lot.
BMC limestone North includes a fair bit of bouldering.
