A variation of the popular 7a L'Imparfait (droite). It starts the same (low sitstart over left) and traverses right to ascend the center of the face using the big pocket out left. (Note that the left arête is off.)

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.
