In reply to Erik B: I reckon repeating the 8c+ is probably the bigger deal although the photos of Knuckleduster look pretty excellent. But like Dave says - he's done everything hard in Scotland so it's nice to confirm his feelings repeating established routes elsewhere.
The fact that he does an 8c+ reasonably quickly whilst on holiday is perhaps the most impressive thing. Of course the guy is training all the time, but the rock is so different from his normal area. It makes you wonder what he would do if he did a Sharma, and moved to Lleida for a winter.
BTW - I normally find limestone unaesthetic to look at, missing obvious lines. But you can't fail to be impressed with that buttress. It looks like a giant has been at it with an ice cream scoop.
