In reply to tallpaulselfridge:
Staying in a bunkhouse or a hostel in a good 'reliable' location, such as Fort William or Aviemore, is probably your best bet. That way you can get out every day if the weather's good. You'll also meet up with others of many skill levels who you may want to partner up with. Getting back to the realtive warmth of the indoors each evening will be something you'll be happy about, as will nearby hostelries with cosy fires and cold beer.
A good and cheaper option that I've done several times is to find a good well-located bothy near to your chosen area, and go base yourself for about four nights. You're very near the hills and climbing areas you're wanting to play and climb in then. Culra bothy, near Ben Alder, is fantastically located for some big winter hills and remote routes. Likewise Corrour in the Lairig Ghru, but it's small and will be busy. Check out
http://www.mountainbothies.org.uk/ for other locations of bothys. It might be cosier in a hostel or b&b, but you'll never forget the experience of being in the bothy in the winter time. Fire lit, happy and chatty company. And peering out of the window at the starry sky, the moon slipping behind the ridge you'll be making virgin tracks up in the morning...
Your best bet though is perhaps to do what you've already done. Pick a good time - and any time in February is as good or reliable time as any in Scotland for good winter climbing. Then, except in the case of absolutely dreadful weather forecasts, just go for it. Go and stay in your chosen lodgings, and just get out and do what your common sense and your ability allows you to do. Don't wait for the perfect weather days or looking around too much for which part of the country has the 'best snow conditions'. And you'll have a great and very memorable time - no matter what the weather and what you climb.
