In reply to subtle:
Go high, go to a location that has a large plateau drift catchment above so will likely have a good depth of snow above to feed water for ice and more chance of the route being complete, go very early, stay in the shade and treat the route as a bonus to the day out. Have south facing rocky scramble option unthreatened by cornices as a back up. Getting away from the honey pots plenty and miles on your legs, a few options on the east.
Castlegates on Shelter stone (though at risk of skiers)
Braeriach, Corrie of the chockstone, or sphinx ridge area (I cannae predict what the cornices will be like), fall back being Angels ridge for something rocky south facing in corrie Brochan.
Or exploration in Braeriach Northern cories at grade I on the way to the above.
Beinn a' Bhuird all four corries will offer grade I or II (again canne predict the cornices).
Lochnagar a quick Central buttress, or romp up Black spout and then down and up the stuic.
