The description on Bleau.info is quite messy, is this starting on the right with an undercling to go to the right for the first move (with a left toe and a right hell hook) or is this starting more on the left for you? 😊 Thanks!
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.
