Supertopo's 'Tuolumne Free Climbs' guide rates this climb at 5.6, just an fyi.
(it also mentions "hexes useful" - I brought a set of WC rockcentrics and used a bunch of them. I know, I know ... "cowbells" and all that :)
Hey Misha, in your description of "essential gear", you only mention gear up to 1.5 inches but part of the route is sort of an offwidth. We used a red friend to protect this (crux) section. I think the red friend is 3.5 inches. The one on our rack is named "Big Red". :^)
