Large queues in the morning in Coire Cas as the funicular was off. Went to Coire na Ciste when it opened and spent the rest of the day there, skiing straight back onto the lift every run. Coire Cas apparently still 'manically busy' - perhaps because of the cloud nobody else could see the West Wall Poma running? Aonach Bowl was in great condition - smooth and fast. Ciste Gully similar, and stupidly wide!
