For all around driving in all kinds of snow, rain, dust, I've always use RainX that counts on 8 different motorcycles and trucks counting U.S.Mail and cars. When I went to Az. in the snow my wiper never got any use. Coming home from Az. in the spring rains and sleet. The wiper were never used. As aside benefit bugs slide off with a damp towel. Also if you watch road racing the leading edge of the wiper arm has a V shape to put down force on the window.
