Cheers for the tips guys, I had extended the sling and am happy clipping after making the move off the undercut for the dishy pockety thing. It's the subsequent foot moves to enable the reach for the diagonal sharp crimp that I fluffed. I'm confident it'll go next time with a bit of care, busting to get back there but haven't managed to track anyine down for Thu/Fri yet.
And re the grade, with the exception of one guy of 6'5" everyone I know has said 7b+. Haven't really done enough at the grades to know myself but happy to take it.
