Might be easier for shorter people because the foot holds are pretty close to the hands. Jumping backwards with both hands feels a bit scary at first but after a couple of tries and some commitment it can be done!
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.
