It was a matter of time, but I finally pulled the trigger. On the ride back from Seattle to Vancouver I tried about 6 different positions at highway speed (no helmet beak on) and pretty much all of them were better than every other option i've tried so far... and believe me i've done lots before.
Just went out today and had helmet beak and goggles on and hit the highway. I am more than impressed. There is still some wind vibration at speed but i'm going to try some vinyl trim on the outer shield and see if that makes a difference. Even if it doesn't I am still one very happy (and broke) camper.
Will hopefully have pictures soon.
