I pulled my wiper arms off altogether and made a smooth coroplast cowl cover. It didn't make any difference in fe that I could tell. Then I reinstalled the driver's side wiper. In the rain, on my car, the drops behaved the same way on both sides of the windshield. That is, on the bottom 1/4-1/3 of the windshield, raindrops just sit there while they blow up and away on the rest of it. That tells me there is a stagnant bubble at the base of the windshield, just like the aero books told me there would be. So now my original wipers are back on.
