Very nice feature. Good heelhook. There's a small ridge on the rock just before the second hold. I couldn't always reach the second hold in one time so this helped me to bum through. Reaching over the rock to the left with the left hand, you find a very good hold to top out.
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.
