I think it could be argued that an area we forget when we talk about drag is body shape rather than body position[/img]. Ten, five or even two pounds of body fat is certainly bigger than most components being discussed. If you took a look at what ten pounds of fat looks like, it's pretty huge.....the wind would see it all. I have no data, but I think most of us would reduce our cda more by losing five pounds in comparison to new booties.
