We got up and tried this last spring. It's too dirty. It just seems like it will never clean up. The moss makes it pretty impossible in the spring - think dirty, wet edges that you just cannot get to clean off. If you could somehow power wash it, then maybe it might be good for one season. So, if someone wants to invent a hand powered power washer and haul up 100 gallons of water up there then we can do it!.
The moves are all there. Feels like 11+/12-, maybe similar to Truth or Consequences but not as good. The hardest part of linking everything would be slipping off dirty holds. For sure there are spots you could get in hooks, beaks and cams. There must be better stuff out there to spend your time on.
Probably best to pull the bolt unless someone else is really motivated.
