Believe it or not I am riding with a windscreen, a memphis shades alley cat. While it is kind of a small shield it cut out all the low-back strain from the no-helmet days. I don't get any buffeting with the 3/4 (love the Daytona sized outer-helmets) but the KBR full-face is such a big helmet it puts the very top of it in the slip stream. I feel like a pumpkin-head with the full face on...
