Diamond 

This is a great friction climb on solid rock. The crux is getting high enough to clip the first bolt. A fall from here results in an awkward slide/fall to an ankle busting ledge. It is definately solid 5.9 here...dont fall. It IS possible to clip the first bolt on Battle of the Bulge (use a long runner). This gives the belayer enough time to yard in rope and jump off the ledge in time to stop a falling leader from hitting the ledge. (trust me...it works!)

Even on a top rope it seemed much harder than any slab 5.9 in Yosemite (e.g., Marginal).

Awesome route. If you are climbing Desperado or Battle of the Bulge anyway, make sure to lead/ TR Diamond before you head out. You won't regret it.
Harder than similarly rated shadow wall routes, be careful.

I dont see how Thin Man gets 5.9 R and this doesnt. I mean, come on, that first clip is terrifying. I led it today for the first time and honestly believed I was going to break my ankle.

PS This is THIN 5.9, not that juggy secure 5.9 that feels all nice and cozy.
