I find the small, competition style goggles, such as the Swedes, very uncomfortable to wear. Granted, in a race, every small factor matters for that split second difference, still, I wonder how much difference does the goggle shape make? Has anyone actually experimented? Is the difference enough to be worth giving up the comfort one needs in long distance swimming? It seems to me the comfort level is in this order:
Swedes "hybrids" with silicone skirts

I think you're talking WAY faster than just sub 25 scy 50's to make a difference. Look at the TOTAL surface area of the outside of a goggle lens. What is it, 2 sq. in? 3 sq in? Now what percentage of that is actually facing a direction exactly perpendicular to movement? 10%? Maybe? The rest you'd have to take a trig measurment of the given angle based on the goggle itself to get the representative amount of perpendicular opposing surface area, and that's assuming the head position is kept the same . I'd doubt it even came out to 0.5 sq in between the two lenses. Certainly the more rounded the goggle the better water will flow past it but you're talking such a completely miniscule amount it's arguable that fixing the wrinkles in your swim cap or not cutting your fingernails would yield more results than choosing an "aerodynamic" goggle. I'd even go out on a limb and say it's not even worth a hundreth to a 50 swimmer.
