I'm 6'4" and went with a Clearview 22 incher on my Road King. I love it. The 'recurve' gives you the equivalent of another inch or 2 of calm air. When on their web-site, check for their clearance items which might have a slight blemish. I saved a few bucks by going that route and still haven't been able to find the scratch. They'll even let you try it out on your bike as long as you don't remove the protective film. Highly recommended!!
I have an LRS on my Road King. It' great. Keeps the rain out of the face a little better than stock. If there was one that was a couple inches taller it would be even better.
+1 on the Clearview. I've had both the stock and the HD touring. I now have a 17" Clearview with a blem that I can hardly ever find. Clearview is the real deal. All of the forum reports on quality and responsiveness are right on.
