Went with a Clearview Small with recurve
Hopefully this will help anyone trying to figure out what size to get:
I stand 5'11", have a 37" sitting height and a 32" inseam.
Went with a dark tented Small (14-14.75") Sport Tour (wider) width and the Recurve, mounted as high as it will go. This allows me to still see over the top of the shield.
So at 68 mph running with the wind at my back or sides I have NO wind noise and can listen to the radio at a volume of 16 (speed sensing set to high) and the slip stream hits me about 1" below the top of my helmet. Running into the wind I have occasional wind noise, but not enough to bother me.
My helmet is a Shark Evoline modular. Turns out 2 years later my helmet is NOT the most quiet out there, but as I live and ride in Texas, I really appreciate the ability to instantly go from full face to open face with the push of a button.
The Clearview Medium as a height of 15-15.75" It would definitely stop the wind noise when running into the wind, but the top od the screen would be close to my vision line.
Hope this helps.
