Did what I thought was a very thorough job of adding foam weather stripping but still have a whistle at and above 45-50mph. Maybe I just need to listen to music louder.

Also I have now gone back and forth between the 11" and 13" shields a few times and have come to the conclusion that the 11" actually works best. 1.25" up from full down at 63* puts 99% of the wind over my head. Looks pretty badass too if ya ask me.
