I have two: an 8" and a 6". I am 5'-10" with stock seat.

I use the 6" around town or when it is really hot, and the 8" on the road. A little wind with the 6" (which is what I wanted), and none with the 8". My wife has no issues with the 8".

I measured to order the 8" size because my RX glasses would move around with the stock "windshield", and I wanted the 6" for looks and more wind on hot days around town.

I love them, and have not had a problem with LRS or their Customer Service. I will continue to use them. As was mentioned, if you leave plastic on you can return it.

Sorry to hear you had an issue. Did you speak with James? He is awesome.
