For snow the MH soft stakes, (parachute kinda things), are the way to go. Looks like MH no longer makes them though, these are the closest I could find: http://www.rei.com/product/725165/rei-snow-and-sand-tent-anchors. I bring enough stakes for the body, and then use deadmanned trekking poles, shovels, pickets, ice tools, skis, buried rocks, etc for guy points. If I am not carrying over and I need to take the guy points with me, I take the tent down and pile snow blocks on it to keep it from blowing away.
