Plenty of routes in Glen Coe starting from the A82, worth doing Bidean again in the snow and the Buachaille is popular - you'll see folk on winter skills courses on the hills here. Wee Buachaille is fairly easy & short in the snow. Check the avalanche forecast before heading anywhere, last year was pretty dodgy.
http://www.sais.gov.uk/ I think Ben Vane is a bit more interesting than Vorlich, with or without snow. CMD arete is amazing on a clear winter day.
Whilst I go out in winter I don't claim to be a winter expert. But........
Not yet been up Bidean nam Bian but it's probably not going to be a hill for me in winter. Best to get some winter experience on straight forward walks first.
Buachaille Etive Beag on a good forecast day in winter is spectacular and yes straight forward.
Buachaille Etive Mor I've walked in summer and yes it's straight forward in summer. Once it has a bit of snow on it it's a different ball game. The obvious usual approaches and exits hold snow and are prone to avalanche. So again not for me, and I'd say best to get experience elsewhere before considering it.
CMD arete I hope to do one day. But in my mind that's not winter walking, it's mountaineering. Don't think I'll ever be heading round there in winter - maybe getting too old to try even if I wanted to anyway!
Creise, did that last winter, it's good fun, but you are climbing the last bit if coming from Meall a'Bhuiridh and careful navigation is required if the cloud comes down.
But there are loads of straight forward winter walks. Do the easy relatively safe stuff to get experience. Think very carefully about anything that mentions a scramble. It really is different in winter! Don't forget the Grahams and Corbetts, it does not have to be a Munro.
Make sure you have what you need to stay warm. Go out with others by all means, but if you don't like their decisions speak up. Study weather forecast and avalanche forecast before making the decision to head out, and remember they are guides not factual statements.
