I've heard this thrown about before. The Europeans have more than enough 'difficult' routes, which allows them to 'protect' some of them, this doesn't just include fixing ladders and cables, but chiselling out hand/foot holds. On the other hand we have precious few such routes and should leave them as is. Shape Edge is another accident back-spot, so perhaps a banister? And before Joan mentions 'elitism', I'd probably need the cable to get up (Broad Stand that is, I can still do Sharp Edge). Can't say I'm much in favour of notices either, however down in the valleys along with the 'No Parking' signs would be a good idea. Trouble is, we're quite a small country (mountain wise). Let those who want to climb the harder routes enjoy learning and using the skills needed.
Now I really enjoy via ferrata, it allows me into situations I wouldn't be able to get to with my gammy hands. But the Dolomites are as easy to get to these days as the Lakes (took us nearly six hours to Langdale last Fri). It's not the ethics I'd argue about, more the lack of routes. Come on then Guy, would you (or anyone in WMTR) like to see chains/ropes/ladders on Broad Stand?
