This is the link-up of the lower half of Yak Crack with the upper half of Reality Check. It is consistently 5.8 to 5.9 on the cruxes for most of the pitches, and combines the good rock on the lower pitches of Yak Crack with the quality upper climbing of Reality Check while missing out the hard and runout crux of the latter route.
