I'm 6' on a 2014 street glide and run the HD 10" wind spitter. The 2014 does have the vented fairing. So my results may be different than yours but I love this windshield. I wear a full face and experience no head buffeting with this shield also you can go to your dealer and demo it. Hope this helps.

 

Get a Rushmore...

I'm good past 100 with my 8" LRS and no helmet, glasses are dead smooth

....or... keep it below 80.

Problem solved.

 

With a tank lift, many experience a reduction in buffeting, all engines like the cooling from the extra air going under the tank (and across the engine) instead of over it.

Here's a thread with a fair amount of info on this subject-
