Nice Bike.......I also own an '09 dyna superglide custom. I bought the Harley Compact Low Profile windshield, and the buffeting at speed is really annoying. Absolutely can't use a full face helmet, a jet-type helmet is a little better. I might want to try the Memphis Shades, wonder if it will work for me? I'm 5'-10", are you similar height?
Yes, I'm also 5'10". I have several full face, the one I wear most is a Scorpion (1000).
I forgot to add!! I mounted the lower clamps backwards!!( I had the same set up on the VROD) It puts MORE rake in the shield so your helemt is not buffeted at the top like a normal windshield. More of my helemt is in the wind so it really is the helmet Aero that keeps my head steady! I also think the buffeting in reduced with the amount of rake. The Mephis shades rolls under on the bottom edge alot more than the Harley shields. I've had several "normal" Harley shields on other bikes ( FATBOY and Deuce as well as my other Dyna) and all produced too much buffeting on my head/helmet.
I think that rolled back bottom edge of the Shades and the angle I run it makes the difference.. You can see in the pic it is angled at about the same angle as the forks, yet the lower edge curls back much more than "normal" windscreens.
If you look at the first "close up" you can see how much the bottom a Mephis shades rolls back under. I think that makes the turbulent airflow under the shield instead of near the top as most common shields.
