In reply to Pete Pozman:
One of the reasons for lack of traffic is that these bays are a bit more sheltered than the main crag, so are greener, therefore get less traffic, so get greener etc etc.
I see chalk and trampled weeds in those sections pretty often so people are climbing them more than you might think.
I've got some historic info the routes and problems there so will probably include that in the Kirklees Climbing guides at some point, probably after the guide to West Nab is finished.
