Didn't get a video but the beta I used was more or less: left hand on good sidepull, right hand on sloper sidepull crimp to the right. High good foot left. Right hand to "good" crimp (the uppermost obvious one), footmatch, left hand to supersmall and sharp crimp. Very high left foot to the left. Go with left hand to left part of the sloper top. Match and mantle!
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.
