I have to also admit to top roping Black Night (E5 6c, but now missing crucial peg) at the Wainstones- given 6c, but more like 6b, should go at E6.
There is now also a stake above the obvious Claybank arete, which i've had a little abseil down as well. The top move looks possible, but very hard (v8 or something) and the gear is ace- a bomber size 0.5 cam a little distance away and a poor size 0 friend right by the crux. I probably still wouldn't like to fall on them though, due to how intimidating this line really is. Maybe H9 7a?
