Because of all this I have developed my own method of presentation as have others. Some are doing what they call CIA constant image area and others CIH+IMAX constant image height plus IMAX.
With these other methods masking may or may not be a problem for you as if you want masking, 4way masking would be required.
Sounds good except I don't want to have to screw around with a lot of masking.

I've been doing this for weeks; too many options to choose from. I'm decision paralyzed.

If possible, you might want to spend some time with it. Things that seem big now likely won’t after awhile.
What's your viewing distance?
As I said, 140" wide scope movies are fine. When I do 140" 16:9 sports, it gets dicey. The size is somewhat OK. Seems fast motion may be the problem.
On the Seymour AV site they say, "We generally don't recommend larger screens than 45 degree viewing angle unless you have multiple rows, or you've had prior experiences and know you'll enjoy it. The apparent resolution of 1080 diminishes past this point, and film's 24 frames per second can show too much judder. Trends, however, are toward ever larger images. The guidelines are increasing and as the quality of the source and projectors continually improve, we're seeing viewing angles break past 45 degrees even up to 60 degrees for slow-panning 4K content."
This leads me to believe the size is too big for fast motion (although only film has judder). From the second row, about 17 ft & 40 degrees, it seems right-sized. Not sure if this is a good plan, but 140" wide 16:9 CIW --- watch scope movies from front and 16:9 sports from back row. Sound wouldn't be important for sports anyway.
