Some folks on the TriumphRat.net forum (Big Twin) have been speakly highly about the
Slipstreamer HD-O Mini Police windshield. $80 and apparently it comes off quicly, same as the slipstreamer shield referenced in this post. I like the classic styling, very close to my Triumph shield. I'd love to be able to quickly remove my shield. May do the wingnut thing like BlueBass.
