Just for the record...
First off, I'm 5' 7", 5' 8" with a 29" inseam.
I ran with the stock screen for a while, and tried all the various mounting positions, and while the stock screen isn't bad, no matter where I ran it I got a fair amount of buffeting, etc. at road speeds above 45 to 50 MPH. If it had one great attribute it was that it was cool riding behind it... Not a bad virtue given the heat wave we've been having in Texas!
I had been extremely satisfied with a CalSci screen I ran on my '06 Yamaha FJR1300, so I decided to give one of their "medium" shields a try...

I got it, but to be quite honest, I was very disappointed in the shield once it arrived. I still have my CalSci FJR shield from years ago, so I had it here for comparison. The new Super Tenere shield's fit and finish were terrible when compared with CalSci's previous work... Rough edges, poorly cut curves, and no matter how much you jacked with the mounting it rubbed the black bodywork on the lower right-hand side (from the riding position). Fortunately the Yamaha bodywork is much tougher than the CalSci material as it rubbed out a tiny section of the shield over time, leaving the bodywork undamaged.
The CalSci shield when mounted appeared extremely upright with little curve to it. Still, for riding at any speeds above 50 MPH it was far, far better than the stock shield, with a nice still air pocket and little buffeting around my helmet and shield. There was still enough upper turbulence to often flip my face shield closed at certain speeds, and especially in certain crosswinds, but it made for a much more comfortable long-distance riding experience... Needless to say, however, it was hotter to ride behind it. It did have one other virtue, but more about that in a minute.
After seeing some pics of the Parabellum screen I thought I might give their shield a try...

I had used some Parabellum products years ago, and they had always worked well and been of exceptional quality. I ordered up one of their "medium" 22" inch shields (which turned out to be only 1/2" taller than the "medium" CalSci when measured mounted... more on that in a moment), which shipped almost immediately and arrived very quickly. I unpacked it, and it quickly became apparent, IMHO, that the finish quality was far better in this instance than the CalSci. Nicer polishing on the edges, smooth beveling, perfect radius curves, etc. Holding the two shields side-by-side really showed the difference (sorry, no pics). There was a bit of consternation about the mounting right at first, as if you try to mount the Parabellum to the stock holes then the shield hits the turn signals in such a way it won't mount. It quickly becomes apparent you have to use Yamaha's upper mount holes for the Parabellum, and then all is golden and it fits like a glove, though it takes a bit more pressure to mount it as it is much more curved than the CalSci (or stocker). Fit appears perfect once bolted up... That is until you turn the bars. That's when you find out the Yamaha handguards hit the Parabellum screen at full lock either way. As it turns out it's not really a problem, as it only flexes the shield slightly when the guards bump into it, though you soon discover the Parabellum material is, by contrast to the CalSci, tougher than the Yamaha plastic material of the guards, as it mars them ever so slightly, though perhaps *polishes* a tiny area is perhaps a better description.
Still, you quickly find out what one of the virtues of the CalSci shield is... Those cutouts on its sides provide plenty of clearance at full lock.
OTOH, in every other way, IMHO, the Parabellum shield is superior. The CalSci may have their signature "vent", but since their shield hugs the area around the headlamps so much little air passes by there and the vent only adds to the airflow slightly to relieve the back-pressure. Conversely, Parabellum solves this back-pressure and airflow problem much like Yamaha did, by providing a nice, controlled gap area between the lower edge of the shield and the bodywork around the headlamp nacelle. As such, despite the Parabellum being quite a bit wider than the CalSci there is actually slightly *MORE* airflow behind it, and it is much more controlled and quiet, too. Very pleasant, and also actually cooler than the CalSci slightly when compared back to back. Better, more effective ventilation is perhaps the best way to put it, with no turbulence. One thing is for sure, everything about airflow is better with the Parabellum screen for me. Less buffeting, despite the actual viewing presence of the screens being literally the same - i.e. I look over the top edge of both about the same. Less turbulence in the cockpit. Less noise. Nicer air pocket. Everything is... just... well... *better*.
And I would be willing to swear the airflow around the shield is far less turbulent than the CalSci. I would hazard a guess that this is because the Parabellum is far more cureved than the CalSci, and it also "lays back" more than the CalSci, which seems to disturb the air less. It also brings the shield a bit closer to the rider, which is usually a good thing.
Understand, they are both good shields for touring and long distance road riding, but for me the Parabellum is just *better*... And because of the, IMHO, far better fit, finish, etc. it is not just a little bit better, but a lot, and for all those reasons a much better value, too.
Please note, I am not affiliated with either of these companies in any way, shape, or form. Just been a satisfied customer of both, and just passing on my personal experiences and observtions about each shield. Needless to say, YMMV.
One thing I know... The Parabellum is on my bike for my 850+ ride to Birmingham, AL.
Anybody want to buy a slightly used (about 1,100 miles) CalSci shield?
