In reply to olddirtydoggy:
Not sure I'd agree with the gully recommendation; as you say, need to have a greater understanding of avalanche risk, often less protection (not that you really need it, but still. ..), possible cornice issues.
Would suggest the classic lakes edges in winter conditions as a starting point, striding/swirral, sharp edge, then something like pinnacle ridge on st Sunday crag, grade II but difficulties avoidable. Snowdonia- bristly ridge/y gribin, crib goch. All come into acceptable conditions pretty readily.
Scotland of course has far more options, and more reliable conditions, but it's a lot further. ...
