Nice 6b that cost a bit but the movements are great (technical ones) with lock heel hooks that help you to go out of the roof. In my mind it will maybe be upgrade to 6b+.
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.
