Topo says to start with the lowest two crimps. So I started with my left hand on the smallest crimp and the right one on the good one. I found the move harder in that way.
Rain sucks, but broken holds suck even more. Remember, never climb on wet rock in Fontainebleau.
The sandstone becomes brittle, and pulling on it will ruin classic problems. Drying it doesn't help, because it's still wet and weak inside.
All you can do is wait for better conditions.
