You are right...the type Spandex shown does not have any real stretch-ability....more akin to Blackout Cloth.
So you really should scale back your screen size to 116" x 206" ( 9.6' x 17') so you have some "Pull & Staple" area.
Exactly which SONY do you have / are you getting? Spandex will eat up a substantial amount of the lumen output. I know it's no too expensive (Spandex) but you will need two layers, and that will amount to 6 yards x 2 (12 yards) @ 60.00 x 2 for 120.00 total.
Consider Flexi-White instead @ 126" x 224" for $169.00. You only need 1 layer, it does stretch 4 -ways making installation onto a big frame all the more easier, and at 126" wide before stretching you could have the original sized screen you were planning on. Also, Flexi-White is 1.2 gain where Spandex will at best be 0.8 gain....a huge variable when you have a 200"+ screen.
Personally, I would advise getting the 126" wide (Tall actually) Flexi cut to 116" so that it can ship "Rolled" not folded. At 116" it will still have PLENTY of stretch to accommodate a 120" Tall sized Frame. Do that and you'll have both the Gain you need, as well as a easy installation that carries virtually no risk of nary a wrinkle.
