I have a madstad. With my givi and the madstad full low and tilted back about 80 percent, great. I did run my stocker with it too. Good, but not as good as the givi. My new shorty does hit me with more wind, but it is clean and smooth. I just mounted it and went from work to the highway then home. It seemed very good though. I'm going to run it for a while, good warm weather coming up here in washington this week. I'll ride it for a while then give another update.
