Things are very touchy north of 1900m on SE aspects on the duffy. We tried to step out of trees today on mariott and remote triggered from 20m away a sz 2 that seemed to run full path. Crown was about 80cm deep and ran full width of open slope(20m+...?). We retreated and followed the trees back down and had excellent, carefree skiing. Pick your terrain wisely.
