You may have seen the wind tunnel test results on Rolf's website. They didn't test the Ardennes but in general Rolf wheels did well. I stopped by their facility and had my wheels checked last month and I talked to them about the test methodology they used. They paid for the test but didn't conduct the test. The same tire and air pressure was used on all wheels.
