Iceman - I put mine on today as well and got an hour ride in before dinner and the rain. What a difference. I'm using my 13" Cee Baileys and get zero head buffetting. I went through four windshields and finally found the madstad system.
If you are reading this thread wondering if you should get the madstad system, just do it. Don't waste your money or time trying to find the right windshield when this system really works. I'm thrilled.
Unlike others, I don't mind the wind coming up from the forged crash bars. The Bakers Air Wings might be my next investment just to calm things down a little or help deflect wind on a cold or rainy ride home.
Good luck with the kewlmetal winglets. Let us know how things turn out!
