I have the MRA speed screen, similar to the one in the op, without the laminar lip. I have adjusted the angle/rake every time I took the bike out or so it seems. It works reasonable well for it's size. I may try the lip to deflect the air flow a little higher, right now it's hitting right at visor level and it's ok up to about 85. Hardware is ugly, it is reasonably functional however. I am still waiting on the Guzzi touring windshield to resurface...
