I picked up the National Cycle Switchblade chopped windshield. I'm 5' 7" and the top of the screen is just about nose level when I don't slouch. If you're taller, the full size screen may be a better fit. I found little buffeting and I think the lowers actually made it worse. I think the reason for less buffeting is that the Switchblade screen is wider than the stock Triumph screens. Note - turn signal interference may result. I made new signal mounts to accommodate the windshield.
I'm still on the fence about the lowers. I'll run a few experiments this spring and see which way it goes.
