A challenging sit or squat start with some tricky moves up an overhanging arete, then powerful dynamic moves to a fun top out. It is a bit reachy but smaller climbers may find higher feet and intermediate hand holds to compensate.
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.
