Sit start on the right on the jugs, and traverse left. This feels like a long move if your'e short, but releasing the heel is the hardest bit. A bit of flexibility helps! The mantle is not that straight forward either! Definitely not the easiest 6a+ in the forest!
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.
