Ascent of La Dalle Impériale as various tick types as sport by Jef Van Alsenoy

Did two laps of the 2 pitches combined. Cool route, perfect for rope solo and a good set of very hard slabwork with nice fissures alog the way to catch your breath. Did the first pitch clean the second time around, fell of on some cruxy bits on the second pitch. Was good to practice switching to grigri to retake the secod pitch from the start a couple of times. Sore feet at the end, man! Has to be a killer route to lead this.
