Beta spoiler. Picking conventional feet I pulled it barely, felt harder than 11c. Then retried it with a high far left foot on a very positive point. Looks like some shoe rubber might be on it. Rock on to get the left shoulder high. left hand can use the obvious edge shaped like a little ledge or skip it and deadpoint to the left side over the block/bulge. Tricky the rest of the way. ANother opinion (E.G.) not logged here says 11c; I agree.
This is a very fun route! I completely bombed the onsight attempt - Pumped out and didn't see where to go at first. But after I made it to the top I went and identified all the holds and it seemed to click. It's all there. Sent it second go with no problem. Fun movement, I want to get on this again.
the crux is on the bottom. Ralph puts up great routes and this one is no different. That said, the first 2 bolts are a little puzzling since the features seem to be farther left of them. Perhaps it's the 4 features or more that jb2100 says he broke off that makes it enigmatic.
