The air wings are better than just using the lower deflectors because you can adjust them to either send air over the motor (legs) or the other direction. I really would like to try them together but I still don't have enough strength to piddle or work on stuff too long. I can only imagine how calm it would be with both sets together.
However, went on a ride yesterday with Cowtown Riders...a meetup.com group. We had 50 bikes and I did about 200 miles. Today I'm not too lively but not too bad.
