In reply to Iamgregp:
This confused the hell out of me when My brother in law who has only climbed SS asked me what the "5c means next to the 6A" in the guide book.
I was like dont you mean 5B for 5 Bolts.
No wait its all top rope...
Checked the book when we arrived and was like what the heck is this system about lol It just seemed it was whatever it was in french -1
Then much later a much much older group of locals were telling some newer climbers the grades to which I realised were the tech grades and made them seem easier than they really were lol
