A couple of weeks ago - while out with Waldo and CruxLuv - I led Robot of Dawn for the first time. Very fun climb with great and steep opening moves. However, there is definitely rock quality deterioration between the 3rd and 5th bolts... Standing on the stone knob above the 3rd bolt, I noted 3 places on the face where rock had clearly peeled off recently (in foot-diameter sections), just where you wanted there to be holds! It required quite a thin and careful ascent just left of where the bolt line seemed to indicate.
It seemed like the thin and unstable rock in that section might warrant an upgrade, at least to 5.11b. I was wondering if anyone else had that sense while climbing it recently. I know Kurt climbed it in late December... Perhaps he'll weigh in. At any rate, just thought I'd mention it!
