In reply to bilbo 1: You may find you can't bring yourself to climb at Horseshoe ever again! Buoux isn't limestone by the way, it's molass (calcareous sandstone) and is more abrasive than most limestones, depending partly on how polished the holds are. Sea-washed limestone can be far more spikey though. Sticks wall is actually called Styx wall - name of the river between this world and the underworld...
