Very cool block in apremont ouest. If you are flexible you can straight put it high on a really good foothold. The move to the top is a bit more tricky but once you have it, you are done!
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.
