Windshield-hugging performance in even the worst winter weather

Thinking about relevance though, and my experience at speeds that would require an airfoil on the wiper, it seems doubtful I would be traveling that fast and need windshield wipers...your experience may of course be different...
PPRO, my first car was a 1963 Dodge, and it had an airfoil on the wipers. If they didn't work at "highway" speeds I don't think manufacturers would waste their money putting them on.
I got caught in some pretty hard rain Saturday night in Columbus, and I noticed that my passenger side wiper was cleaning the window perfectly (with the airfoil) but the drivers side was streaking terribly. (no airfoil).
I agree, RainX is the best alternative to a blade.
