In reply to taddersandbadger:
Yes, it's Iconoclast at Rosyth Quarry that's being referred to. Having possibly one of the last people to climb it before it fell down I consider myself rather lucky. I also know the person who it fell to bits on and I know he updated the comments on the route on UKC to try and warn folk.
Guidebooks are just guides and have information that's current when they were written/published. Rock changes with time. The cracks we use for gear are weakness in the rock and thus by their very nature can grow, rock can fall off etc.
The dolerite quarries in the central belt all have a fair bit of loose rock and lots of require care. Lots of the crags seem to be held together with mud! Personally the only HVS routes at Rosyth I'll go near are The Waullie and Broken Pillar (and bits of that are loose too!).
