I love clearviews, I've now tested Klockwerks (which I loved on my EG, hated on the RG) LRS 13 and several heights clear views. I like the way they come back and the amount of protection they give me.
i just sold my stock height with a vent, I must say that the vent didnt seem to do much, I mean you feel the air coming through it but about half way the tank it disappears.
Anyway, I still have a couple for sale, my favorite windshield didn't have dark tint so thats where I want to go so selling the rest.
See my post in the for sale section (http://www.roadglide.org/showthread.php?t=27172
I still have a GT 13 for sale (dark tint) a GT Med, light tint, and a GT small dark tint.
So if you want to try a clearview for cheap thats the way to go.
