Karl, I've done a few Denny routes that were just this season "rediscovered" through Clint's discussions with him. (Factor, I think, recalls another such route he did with me earlier this season) These latest few sounded sketch enough that I brought a handful of pins. From the looks of the climb (from below) they wouldn't work so I left them on the ground. I got three cams in the only crack like areas of rock. Pitons would have blown the rock apart there, so I'm not sure I didn't have "better" protection than they had. While I was climbing I was especially attuned to Knifeblade or Lost Arrow placements (out of curiosity), since these are hard to replicate with cams. No dice on the first pitch (the second pitch is pure face climbing).
These two must have been very comfortable on Pinns rock, and used a nearly ultimate "pure" approach. I think Dave and I did the second ascent of the route. Maybe in 30 years it'll get a third.
