No Exit 

I've always thought this was quite hard for the grade. The finish (IMO) is a solid V5 boulder problem, though you get a great rest before doing it.

I've seen people pre-clip the anchors with 4+' long "draws" to avoid the last cruxy bits.

12a my ass

Somebody sell me on this route. As far as I can tell based on 2 uninspired go's on lead, it's a mediocre pile of devious 5.10 for maybe 20 feet, then a poorly (yet overly) bolted 10' v5 boulder problem with an obligate tweaky clip off a mono (to protect a fall onto slab). The final awkward 5.12+ effort to clip the chains off miserable slopers removes all remaining aesthetic.
A recipe for injury if you ask me, and a less proud send than the pink-tape route in the gym.

I don't recall there being any need to clip off of any monos on this one. I do remember the mono, but if I recall correctly, you can clip without much trouble using the sidepull off to the right (the sidepull consists of the left side of a rounded hueco). I think 12a is about right. I think Face Off is more difficult and though I have not been on this in years, I would say that the boulder problem is no harder than V4, which puts it right at 12a. The D'Antonio Approach has a boulder problem at the bottom that is more difficult than No Exit and that route is also 12a, so I dunno, 12a seems fair.

And no, hanging a four foot draw does not count....you have to clip off the 'baby butt' sloper at the top.

I had written off "No Exit" as dumb for a while, but got on this route a couple of times in the last month or so and have a more favorable impression now. While the easier bottom half is dirty, the crux at the top is clean and a fun sequence. I think my beta for the crux clips is different. I clip the 2nd-to-last bolt from below, leaning to the right from the obvious crack/seam. I clip the last bolt at waist-level after reaching the decent hold at the lip. Clip the chains after 1 or 2 more moves to the fin just left of the chains, rather than trying to reach it from the sloper lower down. Hope this helps. Maybe if more people got on this climb it would keep the dust off the bottom. It is the next logical step at the crag after Face Off.

Don't know about the grade; the steep crux with big moves is atypical for White Rock. Overhanging is not my style (especially nowadays), but it does seem harder than Face Off and the popular 12a's at BONP in my opinion. More powerful climbers might not as much of an issue.

Led it today and I liked it. There was some dirt but it wasn't bad.

Why clip the chains before fully pulling over the lip? There were a few hard but well-protected moves, then the anchors were easy to clip from the top. I thought it was exhilirating and fun; can't wait to give it another go in the pursuit of a clean send.

That first bolt sure is high!
