Well, I up and did it. Got rid of the +4 Shield and installed the Madstad 14. Still got the +4, not sure if I'm going to sell it or just keep it. I took a short 150-mile round trip yesterday on a very windy day. I am quite impressed. I was getting some air on my face from the side, but the wind was sustained at 30 mph from the west and I was traveling north and south. Zero buffeting which surprised me as I was looking over it. Also went through about 5 miles of moderate rain. Very pleased with the way it handled rain. Because of the way it funnels wind between the two halves it kept the shield relatively clear of many raindrops. I didn't, but I believe I could have raised it up and looked through it with an almost raindrop free view. Had my face shield down and I believe it didn't have as many raindrops on it as with the +4 shield. All in all, I believe I am going to love the Madstad a lot. Time will tell.
