This was really cool. Beta: Taller guys I was with went for the top with their right foot on the good edge that you go to in the first move. I needed to work a left foot onto the lip where there is a good smear, then do a (little) pop for the top with my left hand. Top is good, be brave!
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.
