On a small boulder 60m above Ah, Plus Facile!, in the middle of the slope. Sitstart, climb the overhang with an oblique ledge and exit on the left with the sloper below the top and without the arete to the right.
NB: this is the original problem and the original name, the variant with the arete on the right and the name "Deux Faux Plis en Plats Réels" became popular. The sit start on the right is a project with the working name "Les Sampans Rêvent de Grès".
