I don't know what the true name of this route is or who the first ascent is, but I heard it called Reverse Traverse today and the name fits. This is a link-up of Vile of Crack to Cleft Lip and gives you the cruxes of both routes plus some additional harder climbing as you make the reverse of the crux traverse moves on cracked lip. This certainly bumps the grade up a bit from Vile of Crack and probably puts it in at around 5.11d or easy 5.12a.
Link-up of Vile of Crack and Cleft Lip.
clip the first two bolts of Vile of Crack, then the last three bolts of Cleft Lip, Ends at the two chain anchor of both routes.
