I am not sure if I had the hand wings or not but had the split ones on left and right side my 06 wing and not sure if that was some of the issue but soooo much dirty air. My wife got a lot of turbulence. I tried 3 diff shields and nothing helped. test drove a 2013 f6b, a small windshield and 0 turbulence so thinking could have been the wings. Going to try to stay close to stock on the f6b.
