I doubt this suggestion will be much help, especially since you are buying local, but:
I tried HVMP bar ends and they didn't do much to decrease vibes on the stock bars. I installed Holeshot Touring bars with no bar ends and the vibes decreased dramatically. I know you don't want to change...
Reply sent, and thank you for your interest.
I get the feeling people are worried about how I will react to a low offer. I won't get upset by any offer.
Send me a private message. Someone already has first dibs on the breakaway. If you send me a message then I will notify you if the other sale falls through.
It is the 20" windscreen. I e-mailed Madstad and that's what they recommended for my height, 5'11".
I'm not sure what the exact measurement is - it has both adjustable angle and height. Are you asking for vertical distance or the literal, diagonal distance from plate to screen top?
Edit...
