Very well constructed guide, essential for those who cannot read the German ADAC ski bible.
One comment is that no distinction is made in the Snow category between resorts that often suffer from green slopes and those that never do, but may have lower quality snow due to southern exposure and lowish altitude. This particularly concerns my favorite resort of Saalbach, which gets a lot of snow due to its 'first dibs' position on the Northern flank, but where the south-facing slopes often have white ice or slush, especially in March. This makes it a hundred times better than almost all other medium level resorts which often have no snow at all, or rocky conditions, or cannon-generated ice. High resorts such as StMo regularly have no snow, as well. And Saalbach cannot be compared to the typical low-level (700m) Austrian resort.
