I have never found wind wings to work so I have always driven my Morgans with the side curtains on. I have tried Wind Wings on 4/4 Series 1s, Cowled Rad 4/4s, Plus 8s. My 2005 Roadster has the side curtains mounted on the doors, all the time. My Plus 4 has Brooklands screens, so I don't bother with the side curtains and get all the wind I want. Driven in VA, DC, SC, GA and FL so . . .
Side Curtains allow me to talk to my passenger, hear the radio, erect the top and eliminate the need for an extra large (extra $$) side curtain accommodating luggage rack. I have some Wind Wings somewhere in the garage gathering dust. Do you want them??
Cheers,
Mark
