I've had a National Cycle Flyscreen on my 2004 Speedmaster for 8 or 9 years now, meaning 80-90K miles. It never had done much to keep my face shield fly-free, but it always thought it did a lot more than I would have thought it would in terms of taking that wind blast off my chest. And, I have no wind buffeting concerns often voiced by those with bigger windshields.
I still have that bike, but I recently purchased a low mileage 2009 Speedmaster, with a Clearview shield on a Triumph Roadster screen mounting. It's the right height, as I can look right over the top, and again, no buffeting of my full face SHOEI. This bike also has been converted to the Rivco risers, making the ride position somewhat more "civilized".
But I'm suffocating behind this thing! All vents open on the helmet, and the only wayI can get any air is to crack the face shield.
Riding the '04 with the Flyscreen, on the other hand, gives me air from roll-off on, and in this S.E. Texas heat and humidity, that's as good as air conditioning.
I may appreciate the bigger shield come winter time, so I'm not changing anything anytime soon, but personally, I find the stock risers and Flyscreen suit me just fine.
