Hi Greg, I had a full plexiglass windblocker installed first. There were a couple of issues but the primary issue I experienced was that the reflection coming off it created an annoying distraction in the rear view mirror especially with the top up and especially at night. Also I just feel that the leather covered mesh windscreen presents more of a "factory look" and also is more like the type of windscreen you'd find in a high end sports car. Just a "poser" kind of thing . . .
