In reply to alamik:
It's usually quieter mid week. Routes that have been recently mentioned on local guides blogs, facebook conditions posts or the winter conditions pages here are more likely to be busier. End of Feb is busier. If you want to do a popular route at the end of February on a weekend with a good weather forcast and good conditions then even if you set off at 4am someone else will probably have the same idea. Sometimes setting off a little later works out a better option but you risk getting stuck behind a slower party. As others have suggested, going with an open mind and choosing an empty route is generally the way to go.
