In reply to BenedictIEP:
I couldn't say for sure as I'd not been to Kyloe for a year or two before yesterday. They looked pretty fresh to me but I've (thankfully, until now...) not got any experience of crampon damage on sandstone to compare it with.
Just seen the thread from Jan - not sure how I missed that at the time. I'm really hoping this is the old damage, not some brand new stuff. Hopefully someone local will be along at some point to clear it up (my confusion i mean - not the damage, which is to all intents and purposes permanent)
