In reply to david_angus:
All are good for different things, I know you asked about ropes but with such good bouldering facilities here don't write it off:
AW - not bouldered there for a while but found it generally underwhelming last time I did. Auto belay routes are good. Lead stuff good but grades a bit all over the place. Steep roof that is really good fun but not really like anything you are going to climb on in the Peak so maybe better for holiday training than local stuff.
Foundry - Bouldering most similar to Peak lime and great training for it, limited space but often not too busy, I enjoy bouldering on the wave more than anywhere else indoors. Routes good and consistently graded with itself but maybe harsh compared to elsewhere but that's fine. Main lead wall currently out of action due to maintenance but apparently back to normal by Sept. Auto belays good but can get busy when school groups in during the week.
Depot - Loads of space, really good training facilities, problems basic and powerful at the grade. Great circuit boards. In the winter its the only wall open late on a Sunday eve but I don't know about summer. I really enjoy going here.
Works - the problems are fun and interesting and if I just climbed indoors I'd want these but I prefer the depot style basic and burly for training. Can be very busy, particularly with a younger crowd. There is a new bit I've not been to yet that I suspect is good for the higher grade range. Mini works excellent for the kids, best in Sheffield for them. The kids club staff are very good too.
Hanger - circuit board not great but otherwise a bit like the depot but without the luxury of space. If I was over that way I'd just go to the depot.
Hope that helps
