I bought one from pashnit a few months ago for my gen 2. At 6'2 I couldn't tuck behind the stock screen. If I sit upright with the ZG sport touring screen the airflow still doesn't clear my helmet, but there's no significant amount of turbulence to deal with. I can tuck behind the ZG ST if I want to.
I think the bike doesn't look as good with the ZG ST screen, but it's not unsightly.
Oh yeah, I can actually see the gauges now. I couldn't easily see them with the stock screen.
