I could do the "taller-person" beta, with a left heel and then move up the left hand. Required my fullbody extension, then get the balance to match. Kind of nice move when sticking it.
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.
