Jimmer,

How tall are you, and where does the wind blast hit you? Or does it go over your head? I'm about 5'8", with the suzuki shield, and the wind blast slaps my head around no matter how I align the shield.

"Slaps my head around" is relative . . .  just as is "excessive vibration."

Photo taken early morning, September 12th, 2007 -- I'm packed and about to leave on my L.A. - O.K.C. trip.

Note the windshield -- it is a National Cycle Street Shield, the top edge of which is between chin and nose height, depending on how I'm sitting.  I did not notice the wind slapping my head around at Interstate speeds.  I also did not notice the bike being slapped around by gusts/eddies off the big rigs.  This is likely 'cause I'm more tolerant of a little wind and/or compensate quicker.

When it comes to windshields you have a range of sizes from the 9x9 flyscreen to full fairings that protect the hands and well as keeping *ALL* the wind off the head/body.  

That didn't happen to me 'cept the one time on the Harbor Frwy -- I attributed it to the vibrations of the thumper rattling the eyeballs in the skull.  But then Sluggo noted that the Harbor is far from being smooth pavement.

I'm about 5'10 . I raised the shield about 21/2 inches off the headlight and 2" of slant back from vertical. The wind goes over my head, very little movement of my helmet. I agree with Mr. Paladin a lot of your movement   might be vibration. Hope this helps. Keep asking questions,there are quite knowledgeable people on this site.

That's about the rake that my windshield is set at now. However, it's only about 15" above the headlight. It's an improvement over the two previous settings. However, I think that the major improvement lies in the fact that I'm not bucking 40mph headwinds this week.
