What a line - even the shortened start requires full concentration from the beginning until the pretty demanding bleau-style end on sloper slots. Really worthwhile to try!
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.
