I'm looking at replacing the stock shield on my R1100RT with the National Cycle VStream to reduce turbulence and noise. I also have a 1985 K100RT with a Parabellum shield that is much less turbulent than the stock shield on the R1100RT. I'm on the short side, 5'6" and ride mostly 50 - 70mph. I looked at much of the older threads on shields but didn't see much new discussion. What are your thoughts? Thanks.
