I agree that the Triumph Summer Screen looks great and fits the bike perfectly. However, I don't like the performance. It makes a lot of turbulence resulting in pounding on the top and sides of my helmet. It also tends to pull hot air from the rad up around the knees which isn't so great in the summer.
Because of the turbulence, I replaced my summer screen with a National Cycle Street Shield EX which resulted in much less turbulence when it was adjusted just right. (It is adjustable but the Triumph Summer Screen is not.) It is much quieter because I could actually hear the engine running after installing the EX.
I then installed air scoops on either side of the headlight under the Street Shield which increased the air pressure behind the screen. This reduced the turbulence further and eliminated the wind pressure that seemed to press on my back. It still is very ineffective in cross winds.
Now I am considering the Laminar Lip that Greg mentioned because they claim it also fixes the cross wind problem - according to their testimonials on their web site.
Summary: Buying a windscreen for a Thunderbird has not been a very straightforward process for me.
