Hey Miker I would be very interested in any info about the snap off faring you have. Got any different pics. This wind thing is much worse than riding without a screen at all. let me know where you got and all the feedback you can. I might go that route. 
There a few companies....Mine is from Deadcenter fairings(deadcentercycles.com). There is Hoppe, Dragonfly and Quadzilla. I think. I like the Deadcenter because it is easily removable but lockable to the factory windshield mounts. Some of the othere require bolting on, but I can;t remember which ones. Check some info on the HDForums site,, very good. There are alternatives to the factory (useless) screen..Clearview is one...Order it taller or whatever you need.
I copied this from HDforums:
After a lot of research on this forum as well as others I have selected the Quadzilla Fairing. I am planning on a substantial amount of touring this summer and I wanted to have one for those occasions. I have read where many of you put these fairings on and then never take them off. We will see if that happens to me. No matter, I wanted an easily removable Fairing so I can attachl or detach it when I want.
The attached photos show a test fitting with no windshield attached. I have a fiberglass nacelle that is approximately ¼” thicker than the metal one. So when I remove the Fairing I will have to adjust the brackets to fit better (it is really a tight fit and may be overstressed) for easy attachment and removal and then send it out for paint. The headlight detail shows how the extended nacelle protrudes more than the stock nacelle, a design feature I like.
I offer some comments for those who are considering one of these Fairings to think about. Included are some facts (and opinions) that I was not aware of as I did my research.
I have seen comments that the Fairings are different sizes and that the Quadzilla is larger. I had both the Dragonfly and the Quadzilla in my living room at the same time and placed them back to back. Visually they were identical in scale and proportion and not different to the naked eye. The Dragonfly is supposed to be the same size and shape as the stock Harley Fairing. In addition the shop where I purchased the Quadzilla had one there with the Harley Fairing Bra on it and it fit perfectly.
I have also seen comments that the aftermarket Fairings sit at a different angle. I compared this test fitting to stock Harley and the angle was visually the same. Again, no perceptible difference to the naked eye.
One of the most significant factors to me is that the Quadzilla is sealed on the bottom and is finished to the same quality as the rest of the Fairing. The Dragonfly is open and the Deadcenter has a splash shield. I have heard from others that have these Fairings that this is not a problem and have no reason to doubt them. I just think it gives the Quadzilla a higher quality appearance to it and it makes a more aesthetically pleasing interface with the handlebar clamp. It is difficult to see this on all the internet photos but in actual viewing I feel it makes a difference.
The main reason I went with the Quadzilla is that the brackets are mechanically attached whereas the Dragonfly is fiberglassed into the inner fairing. At the time I was led to belive the Deadcenter mtal brackets were fiberglassed also but it is mechanically attached so they should be adjustable as well. This means I can make the adjustments I need to have it fit properly. I could not do that with the Dragonfly. This is probably a consideration only for those that have fiberglass nacelles.
I liked the inner Fairing design of the Dragonfly better than the others which is why I ordered it. (It has now been returned). However that being said I must admit I like the sound of 200 watts of tunes from the four speakers when riding at higher speeds. It uses the full 4 channel capability that most contemporary mobile stereo units now have.
Although the Quadzilla has metal brackets (the Dragonfly brackets are ¼” thick fiberglass) similar to the Deadcenter metal brackets you have to remove the rubber windshield bushings and replace them with two piece metal bushings that come with the Fairing. It is not as quick an installation or removal as the Deadcenter Fairing.
This is probably more information than most of you want but I hope it may help some who are considering one of these Fairings and they can add my comments to the others.
They are all quality products and the choice is difficult. If I had my choice I would want a Fairing that has the features I find most desirable from all three; the inner Fairing design of the Dragonfly, the quick detach and locking system of the Deadcenter mechanicaly attached brackets, and the sealed bottom and mechanically attached brackets of the Quadzilla. In the end I went with the Quadzilla, primarily because of my attachment issues, but was pleasantly surprised as I found it had features I was not aware of. It is a good fit for my bike and me. I will post better photos when I get the bracket work done and the Fairing painted.
I don't have any pics on this computer, I'll post some to you when I get home to my other one.
