RE: Talk to me Martin - the (anciently chipped) right hand crimp that you start from has had bits fall off it since the guide came out. This used to be sharp and positive across its whole width, but now the index finger side of it is a bit more slopey. Don't know if this affects the grade, only that I did it once when the edge was still sharp and can't do it now, though that could just be me being fat and weak.
Also, I don't recall using any pebbles for feet, I went from RH crimp and LH slopey/crozzly crystal thumb catch thing up to slopey dishy thing with my left with left foot in big, low pocket. Then right foot into higher big pocket on the right (blind) and right hand onto gash sloper just above the dishy thing (crux) and go again with right to finish. This sequence could be wack, as I've never seen anyone else on this problem.
Dunno about the grade, only done a handful of other 7b+'s and no 7c's so don't really have a frame of reference.
