What a fun two mover to climb! A boulder for the warmer days because it’s often wet. First jump to a good hold, then mantle your way up. Especially the preparing footwork before lift off and the straight body position afterwards.
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.
