This block has several lines on it, so lots of variations to chose! The first dynamic move took me many tries to stick, because it’s almost at the limit of my reach. For taller climbers this move is a bit easier, but probably the top-out will be a bit harder.
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.
