In reply to Darron: Hi Darron,
Yes, they are on the last but one level. The routes you were doing were, I think, on another orange wall which is about 50m to the left of our routes. They are also fairly recent but I don't know any of the details. You might find something about them on the V12 website
Our routes, which we only completed yesterday, are listed on UKC logbooks as Prelude to a pint 6c, The whole of the law 6c, Hard Times 6c and Rejoice 6a+
