Sorry, Rockfax, but it gets a lot easier than this! La Reine des Bouses which gets 4a/4b in the current local guide is considerably easier than this. The slabs at the start are really quite difficult even if they don't look it from below. Incidentally, the latest guide gives this route 4b. Rog Wilko - Lead - 02/Nov/14
