I received my Madstad bracket and 20" wind screen this week. I had just finished a 1000km trip through New Brunswick using the stock screen.
So far, there is a large improvement in buffeting. I took the bike up to 150km/hour and had no impact on my vision, whereas with the stock screen, my vision would blur from buffeting at about 120km/hour.
There is still wind hitting you, as these screens are designed to allow air underneath. The difference is that it is smooth clean air that doesn't rock your head all over the place.
