Here is my experience with the Madstad wimdshield for my 2019 790 Adv S: Agree with @JJ99 that fit and finish is top notch. I am 5’8”, and got the 18” screen because I want to be able to see over the screen. I tried every combination of angle and height and the Madstad did not make any noticeable improvement over the stock S screen in the high position. I tried with both a LS2 Pioneer ADV style helmet and a HJC Rpha modular. No difference noted between the two. The Madstad looks horrible on the bike as well. I returned the Madstad, they gave me my money back minus 15% and shipping costs. Next I will try the stock screen with an MRA x-creen spoiler. To date the best solution to eliminate buffeting Ive found is to take the windshield off completely. Second best is S windshield in high position and “winglets” removed. The bike looks horrible with no windshield, and it leave my gps completely unprotected.
