I don't think that size is the critical issue here. We know how big the Renaissance block is, and this wall/bluff or whatever it is, is clearly of a similar scale. The real question is whether it is a bag of shite or a stunning clean piece of rock with just enough holds/features in all the right places and a perfect landing? Unfortunately the odds are stacked against the latter, but you never can tell...
I'll send Commander Craine for a look, he loves stomping around discovering new bits of rock.
