If you want to get some SCIENCE involved, I was looking at the Lattice data the other day (I work for them) and V10 is roughly what most people climbing 8a+ can typically manage, so if you add a bit of rope-faff factor, then hard 8a+/low 8b is about right.
I also did the next three moves off a sling clipped into a bolt which takes you to a ledge you can sit on.
