Slipstreamer 34 inch windshield

[piekielrl]

Hi all, I have a 97 GL1500A and the stock windshield is just getting too many micro-scratches due to its age. I've tried polishing them out but the screen still glistens in the sunlight, making riding sometimes difficult. I see that Slipstreamer makes a 34" windshield out of Lexan. Am I correct that 34" is WAY taller than the stock screen, which I believe is a 27? When I have my vent open, it is comfortable in the cockpit. When I close the screen vent (on cold days) I get a lot of buffeting. Any advice here, regarding screen height or methods to reduce buffeting would be appreciated. What about the discontinued "Winglets" that attach to the side of the screen? Thanks, Bob
