I'm thinking of swapping out my OEM shield for the V-Stream shield. I'm 5'9" & usually wear Arai XD-4 when I ride with the shielf position at its tallest setting. I've noticed a slight 'buzzing' and occasional severe buffeting at times during my ride. I noticed the wind just hits the leading edge of my visor and seems to create slight 'vibration' leading to the 'buzzing' sound. I tried lowering the shield to compensate and the wind just blasts me under the visor and hits my shoulders rendering use of my GPS/music uselss due to excessive wind noise. So, I thought I'd go slightly higher (V-Stream Shield) and see how that goes. For those who is using...or have tried the V-Stream shield, I'd like to hear what you guys think about it! Thanks!
