In reply to GCW:
Lots of confusion here, which I'll try and clear up. I know of three ascents. Joe, Phil and myself. Pete has top roped it. I don't know of others though, of course, there may be a few. I very much doubt there are many though and certainly not nine. It is very unlikely that any of the ascentionists listed above will have voted on it - I know I haven't. The V10/Fnt 7c+ it is now given comes from Pete and Steve Dunning, who has been on it. It is extremely likely to be undergraded.
Johnny to the very best of my knowledge has not done it (and would struggle with the reaches anyway). Grading practices at Pex are nothing to do with Johnny who has done nothing significant there. Grades have traditionally been harsh and tech grades only because the place, in its heyday, was seen as a training venue. E grades were not need in the normal sandstone ethic. Remember the stars then (Phil and Joe) were extremely proficient and bold trad climbers. To my mind, the two different ways Monoblock has been done are not hugely different. In fact, Phil and I took a straighter line, Joe starting right and then moving a little left. No-one knows which is hardest/easiest as no-one has done both. I took the line I did because that's where I thought it went, not having asked anyone in the know. Hope that helps
