Really cool short 7a with a nice low sit start, two pretty good pinches, followed by three tricky slopers and a kind of a long move out to the right. Shorter climbers would need a bit more foot sorting and hand switching. High right foot for the top out. Make sure you visit when temperatures are low.
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.
