On the West side of the corrie, there are a couple of options that are more amenable than the 3 main gully lines.
A short gully (sometimes banked out), bounded on skiers right by a squat buttress, is an obvious choice, and possibly the easier of the options.
Slightly back up the ridge a short way is a wide relatively shallow slope/bowl (depending upon build up). This feeds you into a narrow, slightly steeper snow runnel, which is hidden from above. It's a good line to scope out from the corrie before attempting, so that you are sure about the state of the lower runnel.
