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.
I don't have a big span but it felt easier for me to reach out to the ledge instead of taking the crimp near the starting holds... Sorry, I don't have a video of the send, so I had to cut it together and you can't see the topout.
