Please respond only if you have actually used both types of fairings. I need product tested feedback, not opinions (sorry to be so blunt). I am considering buying an expensive handlebar mounted fairing (Parabellum Scout). I have had a Vetter Windjammer III for 25 years, but am looking for something more aerodynamic. Is there anyone who has had both products? What can I expect in terms of:
1. Wind and rain protection
2. Noise and wind turbulence
3. Handling (especially in wind)
4. Gas mileage
5. Durability
6. Finish and overall craftsmanship
Thank you for taking the time to respond.
