----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- I fly window open all the time with my Bubble Coupe. I can't give you the why's and wherefore's, but I do know that the bubble is more aerodynamic than the flat shield. I'm actually more inclined to bring the passenger side window up and over center, thus giving me open windows on both sides, but a sun shield overhead. I also figure that this overhead config. gives better lift on takeoff than both windows down. As far as my reasoning for the aerodynamics of the bubble, take a look at all racing farings on motorcycles. They're all bubble style. No flat shields out there. The flat shield pushes through the air causing much turbulence behind it. The bubble lifts the air and contours it up over and back down behind the canopy. No turbulence, and increased lift.
