Anyone have recommendations for quiet helmets? I upgraded last year from my 5 yr old Shoei TZR to a brand new RF1100, first time I spent so much on a helmet. I find it very loud compared to the TZR. I have adjusted the shield multiple times to no avail. The shield also doesn't sit flush with the rubber gaskets on the helmet & there is ALWAYS this annoying whistling sound which drives me nuts. Yes, I wear ear plugs & most of the time on my commutes I either have my music on or I am listening to an audio book.
