I have a Slipstreamer Turbo S-05 Windshield on my bike which keeps most of the wind off my chest and hands. It unfortunately directed the wind to the top of my helmet so I added a Laminar Lip which helps but I still get a lot of wind noise. I had hoped to be able to give up ear plugs on long trips but so far no luck. The other thing to be aware of is that with a large windshield cross winds really affect you.
