In reply to Pay Attention:
That's a full day out. If the OP is looking for a quick route to fit into a journey then maybe something on the Buachaille to get the high start?. Easy Gully next to Curved Ridge maybe? Or one of those gullies on the L flank of the Little Buachaille?
Or one of the gullies on Sron na Creise, which aren't too far from the ski centre?
