First...I've found through many showings that Super 8 scope can be shown on at least a 16 foot wide screen, which is what I use at my house out by the pool...BUT ...to make it presentable, I use the Elmo GS, with a f1.0 lens, the best lamp available..two blade shutter in it...AND the screen is painted with Steve Osborne's miraculous special screen paint which adds ...and I do not exaggerate...about15 to 20% more brightness/white-ness.
On the subject of inflatable screens....I have used one for outdoor shows away from my house..mostly at church events and they have their ups and downs, so to speak. On the good side,
1. It's the 12 foot measured diagonally version and it goes up very easily and quickly.....BUT...if you have any amount of wind, trying to get it erected and staked down to keep it from falling over forward or backward...well, it's like trying to moor the Hindenberg airship in a hurricane. It can be done, but it's a long and sometimes frustrating business.
2. Mine, and most of them I've seen, seem to be in a Hi-Def TV format....neither actual wide screen nor standard old time squarish format. if you want to fill the screen to the black masking, you have to zoom out to do it...and you lose top and bottom of a standard format picture. If you are showing scope, you leave A LOT of space top and bottom. But for my church Trunk or Treat Halloween showings....it's fine.
3. and when it's not windy, it deflates in no time and packs away. but DON'T EVER USE THE SCREEN PAINT OR ANY PAINT ON IT.
Steve Osborne tried it on his and the paint added just enough weight that the blowers could not support the screen.

Robert, I have posted replies on this topic a few times on the 16mm forum.
I have been doing 16mm outdoor shows since 2011 or so. I custom built (using 2' x 4's) a 12' x 16' screen, representing the approx. 4:3 ratio used on non-scope prints.
Attached below is a picture during the initial setup (about a week before showtime). It was supposed to rain, so that's why you see canopies in the yard -- to cover the projectors. At the time, I was using (2) 80-25 Kalart Victors. Both used the newer halogen bulbs (200 watt), F1.6 lens, 2 blade shutter. Picture was ample bright in my opinion, no complaints from anyone else. Issues I found were with the screen (more below). First year was a double feature -- Peter Pan for kids, Invasion of the Body Snatchers (50's) for the adults. Ever year since we do a kids/adult setup. Last year got rained out, so for this year it's Toy Story for the kids, Beetlejuice for the adults.
I had come across a B&H 2592, (brighter) 250 watt Halogen bulb, 3 blade shutter, AND, faster F1.2 lens. I noticed quite a brighter picture with that setup, despite the 3 blade shutter. I attribute that to the faster lens and slightly brighter bulb.
I have since upgraded to a pair of military B&H 2585 (also known as the AML projectors, the ones sold new on Ebay from Iceco). Those projectors are essentially the same as the 2592, EXCEPT they have 2 blade shutters. This combination of shutter, lens speed, and bulb is probably the brightest you will find, aside from going to Xenon. I believe some of the Eiki's also made 2 blade shutters with a F1.2 lens/250 watt halogen, too.
Suffice to say, while the Kalart's did the job, these are much better.
Regarding the screen, the first year I used a nylon tarp I bought online (which was just under 12' x 16' by an inch or so). As much as I stretched it, as the night cooled, it "shrunk back", resulting in wrinkles. The next year, we laid it out in the sun all day and stretched it while hot/smooth. That helped a lot. We also painted the back black to avoid light passing through, and eventually painted a 2" black border on the screen. Last year we rebuilt the frame using 1' x 3' for lighter weight. It was anchored inside the bed of a truck for proper height, and anchored like crazy since at that size, it's essentially a kite in the wind.
Future improvements will be changing the screen material to something else -- still in the "what should I use" stage, but I will let you know what I come up with.
Hope some of this information helps you out!
