I installed my tinted Klock Werks shield today and just got back from a test ride using two different helmets. I found that with my Bell half helmet I was getting a lot of wind noise on my ears at highway speeds. Smooth air flow over my helmet, but wind bouncing around the ears that would definitely get uncomfortable on long highways runs. When I wore my Shark Evoline modular helmet in 3/4 mode the wind noise was significantly less and I think this will work out for me. The real test will be when I ride to the Ozarks next month which will be a long weekend ride.

Here's a pic with the tinted shield. I had to make sure the fast red F6B was parked, otherwise it's just too fast for pictures
