In reply to Alkis:
Very familiar story - I mentioned “a couple of exceptions” in my original post as although I find most indoor walls to be softer than outdoor, there’s an exception to every rule!
The wall at Foyleside Derry I find very hard in the grade. Not to give it the biggun, but I can’t remember the last time I didn’t onsight a 6b+ lead route, indoors or out. They’ve got one there I could barely even get to the top of this Xmas, let alone onsight. Easily 7a at any of the London walls I climb at. They’ve got 6a+ there that would be 6b+ at The Castle etc…. I’m not complaining mind, it’s a fantastic wall with some brilliant setting and is cheap as chips, you just have to recalibrate your mind a bit!
As I said to someone at the time, if there weren’t grade discrepancies what would we ever talk about?!
