Limestone is defo too soft for trad climbing as you no doubt know, but for bolted sports routes its just fine. Most of the routes are well maintained and re-bolted regularly, and re-anchored too. Come check it out one day....

Would love to, but the way things are going the chances of us affording to travel ever again are remote.

That's a stunning, yet slightly unnerving photo, with those precarious looking spikes. Was this an area you climbed yourself? We don't have any bolted routes locally. Would probably have to travel a bit for that. I haven't done lead climbing for over 20 years! I like the freedom of bouldering.
