Unlike on the bleau.info video I went up left hand first. Left foot on the good foothold and right foot just against the rock. The key for me was to do the sit start without a crashpad because my right foot kept dabbing on the pad after the first move. Awesome area!
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.
