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.
What about the combo of WW and V4"V7" without the crimp up and right of sloper and straight up to juggy rail from middle of WW traverse (after matching sloper and using pinch in middle of traverse)..... this felt nearer V7 than V4, maybe the crimp is crucial at that grade?
