I'm looking for a GT Grand Touring windshield. During the cold season I attach my OEM windshield to the top of my Vario screen replacing the 3" adjustable extension and it's a total height of 21". This height eliminates any wind noise and wobble to my helmet. I would like to try one and see how much wind gets eliminated totally. I know that there was a demo being passed around but haven't heard about it for a while and am willing to give one a go if available.
