Many personal opinions here now.....
I my experience, a run-on landing (with skid or wheels) only work as long there is very little snow, and you are sure about the surface below the snow. With more snow on the ground (or unsure about the surface below) the high hover is nearly the only safe technique. But with larger hcp's and dry light snow, it never stops blowing snow. A very good reference is the only safe thing.
