I put a layer of Rain-X on my windshield, and have teflon winter wipers from crappy tire, and they never make a sound, even in the intermittent rain, because of the Rain-X. I can see usually get away without using them in most rain at higher speeds because the water just slides off the windshield and at higher speeds still do quite a good job without lifting (again, because of the Rain-X). I recommend winter wipers (with covers that prevend water from freezing on the blade and warping it) and putting a layer of Rain-X on the window.
