^ Spin, I knew An Teallach might raise an eyebrow, but you never know if you get the right timing... . I would definitely include Creag Meagaidh - there is an obscene amount of snow high up, and easy gully is more banked out than I've ever seen it (unbeliveable cornices on the Post Face though (and might not meet good skiers definition of steep?)). Obviously you are likely to have a longer walk in. Same with the Mamores and other bits in the West, there has been some massive deposits in places and if conditions are favourable (or there are further significant falls in the spring) then there will be stuff other than the usual suspects to consider for a while. If there is a hairdryer or prolonged wet spell, then its a different story of course.
As an aside, last year I skied on the Cheviots in June. But probably with more bike: ski ratio than your route on Braeriach (nice combo, especially if the travelator is relatively complete). Ben Alder another one for bike/ ski trip that I missed last time.
