Precise heelhooking, slopers squeezing and a bit of compression will get you up this beautiful classic. Short people will have to start with a smaller right hand than others, but it gladly doesn't make the boulder any more difficult!
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.
