This is one of those lines that sucks you in. You'll get up to the slopers on your first go, and they don't even feel that bad at first. But the mantle is crazy hard no matter how you go at it (and there are a few good options). In the end it's more about perseverance and belief than anything else.
Ce bloc fait peur mais n'est finalement pas si dangereux avec une bonne parade!
No Climbing Today!
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.
