Mako Windshield owners

For owners of the Mako windshield how does your passenger like it?
I am 5'7" and i bought the 11 inch shield based on what other members that were the same height and what their website suggested for me as well.
I went for a ride today and the wind hits my glasses and causes them to move on my face.
So I will be sending it back and getting a taller one.
But as I was riding I was thinking what size would work best for me and my girlfriend.
If I go up to the 12" inch windshield that will probably take care of me but not my girlfriend.
I don't want to go super tall but I really don't think the 12" shield will work for my girlfriend. I think the wind will still hit her in the face.

So owners of mako shields I would like to know what your passengers think and what size you are using and your height.
