I am interested in a windshield for my 03 BA.I am concerned with buffeting of my large head. It happened with a windshield i just put on my 76 honda 550 and made for an uncomfortable ride. There are so many different heights an shapes and makers and prices. You have been a huge help with all my newbie questions i appreciate it
I love to go swimmin with bow legged women!

Lots depends on your height . I'm 6'0 and have a Memphis adjusted just below my line of sight and have no problems .

Fast Eddy is the vendor of choice for windscreens and lowers that fit our bikes, he has skype, start a dialog

I have a 17" Memphis Shades "Fats" screen on my '02. You can use Suzuki Maruader hardware (MEM9907) to mount any of their screens. I bought mine from Cruiser Customizing. The new screen mounting systems are toolless removal. My screen comes off ,but I have to loosen allen bolts. I really enjoy the removable feature. Previously I had a Triumph Roadster screen.

It makes us (well, me anyway) feel important.
This is a topic I always find interesting. You see Bill, in many (perhaps not all but many) cases adding a windshield makes matters worse. Case in point, the buffeting you pointed out when you mounted a shield on that 550 Honda. And it's not the windshield's fault really... what I mean by that is you can switch to another shield of a different size and proportion, and still end up with that nasty buffeting.
I run with a Memphis Shade Big Shot. Like Al, I love the quick release aspect of it. But to fix the wind turbulence problem I added lowers as well. There have been many discussions on shields and lowers so rather than type it all out again, have a look at this thread for more info.

I've had three different screens on my America. At 6'2", these are my impressions:
Triumph Roadster - looked good, a lot of buffeting (I had to switch.)
Triumph Tinted Flyscreen - looked great, minimal protection, some buffeting,
Windvest - neutral looks, fair protection, little to no buffeting
I sold the Roadster Screen and Flyscreen... I kept the Windvest.

"Alley Cat" and I think I got it from Fast Eddy , it's less obtrusive and doesn't look like a plexiglass barn door .

Windscreens. Most any one you choose will still require that you clutter up your lower fork shrouds with little wings. The air flow from below must be acquitted. Even if the glove fits.  Cinnamon Girl came with a summer screen. Riding her home through Oklahoma in the Summer of 2007 that screen just about became a 'Frisbee'. Vera Lynn's Roadster screen is leaning up against a closet wall as is CG's. Screens? Try a full face helmet and leave the screens on the porch. Of course this advise is from a Floridian, where freezing temps, sleet, freezing rain, and snow are analogous to hens teeth. Matt (Mlessard) gives ole man winter the finger without using a screen. gotta admire them yutes.

That's my take as well.
27 degrees fahrenheit on the ride in to work this morning, but my full face helmet, neoprene half mask, Firstgear thermo suit and Choko Claws made me wanna keep heading toward the mountains.

Ha! You had me beat. Only 54 degrees on my ride to work today.  (Halfway to work I did notice I had forgotten my neoprene neck sock.  )

Triumph has upgraded their accessory catalogue to included some new screens (as well as backrests, floorboards, etc etc etc) and quick release mounting brackets. New screens look larger than the ones previously available. (Pick your model, America or Speedy then choose screens.) Expensive.

I modified my 17" Fats by cutting out holes on each side to clear my driving lights (unlike the Roadster, the Fats doesn't have this provision). That gap on either side must be just enough to disrupt any turbulence. I like riding with an open-faced 3/4 helmet and it is pleasant. When I pop the screen back on in October, I'm amazed how nice it is riding behind the screen, particularly on the interstate where I'm not required to hang onto the bars for dear life. That makes the screen worthwhile to me. Of course, I had the Roadster screen and didn't feel that had any real buffeting issues either. Guess I'm just the right size?

What's the deal with Windvest and what makes them so good?

Windvest screens are thicker and the brackets are heavy duty,I had one on my 2002 TBA.Most other windshields are cheap and the hardware is crap as well, but thats just my opinion. I just enjoyed the one I had and would buy another.....well worth it.

So do others.
I didn't say they don't.
But now that you mention it, I will say the Triumph Roadster screen and the Slipstreamer Tombstone unequivocally DO NOT work for me.

I tried a WindVest on my 05 America and didn't like it. They are a great company and allowed me to return it. Its protection area was a narrow envelope and I didn't like it. This lead me to work with Clearview on developing a replacement for my original Summer Screen which was awful for someone 6' tall. I didn't want a large wind shield which is one of the reasons I tried the WindVest. The large Roadster screens are way too big for me. I just wanted the buffeted wind to hit at the top of my head - not in my face like my original Summer Screen.
I've been extremely happy with my Clearview for over 4 years and couldn't imagine anything better for me and my bike. Obviously, there is no perfect screen for everybody.

All this talk about airflow. Having a full face lid as a screen a question arises, "why do modular lids have air vents?" It is not like they don't allow air in the helmet already. Answer? Rain collectors.

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.

Would be cool if there was a wind tunnel simulator we could run our setups through before deciding on a particular configuration.

That would be very interesting.
I run a set of wired ear plugs sometimes using my GPS to play tunes and give directions. The wind behind my Memphis Fats shield just gently plays around with the wire that runs to the windshield. It would be interesting to tape some ribbon strips to each windshield and see how they moved around. Than, add lowers, etc. and see what changes.

I tried the streamer taped to the top of the shield idea.
I tried taping about 15 or 20 two-inch pieces of yarn along the top of my shield. (It looked dumb but this was a scientific experiment, eh?) Without lowers, the pieces of yarn vibrated wildly in a horizontal, if not downward, direction behind the top of the shield. With the lowers in place, the yarn blew upwards at almost the same angle as the shield.
I feel the lowers have to be set up to introduce air behind the shield to decrease the negative pressure behind the shield that tends to pull turbulent air down on your helmet.

Yes something like (near the bottom of): http://www.bikehps.com/mra/variotouringscreens.html
This looks like finite volume computer fluid dynamics. It used to take a main frame computer to do these runs but now they could probably be done on a modern pc. I bet there are lots of people running these programs at work to simulate proposed automotive, architectural wind effects and other new designs.

I don't know what gererated their picture but I tried some simple 2d experiments using a compuational fluid dynamics package for Gerris. Very tough to make a model, very slow to run, very hard to interpret the results.

Since the screens are rounded and some air flow is lateral and some is vertical, I would think a 3D model is required. Gerris will take a solid 3D model so now all we need is a solid CAD model of a modern Triumph with windshield that we can change angles, dimensions and add lowers to .......
