I did the retour last week, around 7C too, seems harder than the aller version, especially for shorties, you can see my beta on @carosinno Insta (haven't put it on youtube yet).Also the trav was surprisingly very dirty and chalked up for such a not famous line!! Such a pity...
One of my favorite trav in Font. Truly amazing! No long reach except for the crux where I had to be a little creative in comparison to the men’s beta. You can see the beta on video. People upgraded it to 8a+ and I also think it’s right. Dries very fast and needs to be an overcast day because otherwise it is a bit warm for the slopers.
A must done for shorties with strong fingers. A test piece of crimp power endurance. Better for mid season because the area doesn’t dry fast. Also sit start is required because it’s one of the hardest move. But sit starting on crash pad is accepted by bleau.info people and doable for shorter people.
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.
