Did Walnut Whip yesterday at Baslow, and also did a finish across Little Richard to the arete.... (which incidentlly felt about Font 7b+ - as the finish via the jug felt very soft)
You make your best guess and then just hope people will show some understanding if you end up offmark.
When I checked these problems out, I thought that Choker was the more logical (least eliminate) of the two traverses. I assumed that the line of jugs wasn't in on Walnut whip, as if they were it was no where near 7b+ (or B10). So traversing on a line one foot beneath the jugs seemed a very artifical eliminate, whereas at least on the Choker the jugs were out of reach.I would go and try the choker, but I don't think that I would bother with Walnut Whip. Unless I have got something wrong in my perception/ interpretation of the problems.
If you enlarged the boulder by about 5x you could almost be in hueco.
When I did this I thought it was pretty tricky. Didn't know where it finished though, I kept going low round the arete which is possibly a tiny bit harder than finishing Little Richard. I felt it was harder than 7a+ anyway, confirmed by Johnny Brown who couldn't do it. Nuff said!
I ended up very low on the arete at the end I think, pretty sure I wasn't up where your chalk is. Probably did WW into end of Choker without doing any of the hard moves in Choker = bad sequence. Apologies, just ignore me.
The sequence Dave told me is very pleasant on WW and is, as has been mentioned V7. Me and cofe had a good session on the back of the big boulder and climbed some nice problems (some of which we are sure must be new- or not done for muchos anos). The best of the ones we did was a technicalish slopey groove/mantle, and many sit sarts to easier problems.
