In reply to Father Noel Furlong:
Full on winter day expected on Saturday. In snow, high winds and quickly dropping temperatures I expect to have to use all my winter skills to battle my way from the car park into a certain Speyside hotel for my free lunch.
If you are committed to doing it this weekend then I would spend Saturday doing wilderness stuff not too far from the road just getting used to the kit and operating in winter conditions. Nothing to stop you giving somebody their first taste of wearing crampons (and of balling-up!) on a flat snow-covered path.
Less loaded western slopes on Sunday might provide something more interesting. However, choosing a weekend with the prospect of more consolidated conditions might be the best option.
