Testify is the second bolted line from the left side of the wall. It lies just to the left of Finger Prince. I recommend you clip a long draw first into the double bolt anchor to the right of this route. It will help keep the rope from flossing you if you fall and doesn't add much rope drag.
You're going to either love or hate Tesitfy depending on how you feel about handjamming. I liked the route even though I suck at jamming. Move up the seam and fight your way into and out of the double hand jam slot. A few jug moves later and you'll be at the best roof crux on the whole wall.
This route in Rolofson's guide refers to "painful fingerlocks" and didn't get much in the way of stars. It's actually a fantastic route and deserves more traffic.
Anybody out there got any beta for this supposedly best roof mantle crux on the wall, cause I think it frickin' sucks. Guess I'm just not used to fingerlock, hand jam, slopy topouts with little to reach for, but it seems a bit above 12c. Maybe I'm missing something.
If I remember correctly, there is a micro edge above the roof, that makes turning the lip only a semi mantle. It has been a long time, so I can't offer more beta than that. Fun Route.
