The first very powerful move ends in a painful sidepull. After matching this central crux hold you have to pull far to the right top hold. Really cool and technical problem.
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.
