Just installed a 12" dark smoke Windvest on my 2015 RGS. What a dramatic difference. In clean air virtually no buffeting. Even in heavy traffic the buffeting is way better. Previously couldn't hear the stereo or pipes at 70 mph. Now can hear fine at 2/3rds volume. Height is great, I'm 5' 11" and tend to slouch a bit. Factory seat. Haven't tried it at night yet, but during the day I can see through it fine. I, and more importantly, my passenger are very pleased.
