WOW! That is massive. Do you have enough brightness? What kind of screen do you have?
I use
this and it's super affordable. Very affordable. AVS sells 'em too. Projector People as well. You can custom order, for a very nominal sum. I added CSR and roller casing in custom black, and all of that was maybe only $100.
The issue with using this screen is being within the "viewing cone". IOW, you want the PJ close to the height of your head. Couple feet is still fine (but closer means brighter). Doesn't matter how far in front of you, or behind you, only the angle. Also, the width of the seating arrangement matters. You want them to be within 20 degrees. The number doesn't sound high, but that's still a lot of play. I use two rows of four. I honestly cannot detect the difference in brightness between ANY of the seats, except for the extremes of the front row only.
I got mine as a manual, and it's less than 1k shipped for a screen that is larger than 75 sq ft. I highly doubt you'll go that big, and therefore highly recommend a fixed screen.
Some say it's actually cheaper, if willing to do DIY, to buy the manual, rip the material out, and then fix it yourself. I don't recommend this path, because firstly the material is super stiff with basically zero give, and the emuslified glass is something you definitely don't want to scratch, or else you'll always see that scratch. Otherwise, some say it's a tough material and it's hard to destroy... YMMV.
Brightness is fantastic. I find high lamp mode to be too bright, even with my older bulb at 836 hours. With my new bulb, I actually raised the PJ some more to reduce the retro reflective effect. I recommend a ceiling mount if using this screen, for this kind of adjustment flexibility. Ok, if using wall mount, just make it so you can play with the height easily enough.
It looks like an enormous plasma. I've had people over who were absolutely confused. They even asked, "What the hell kind of TV is that?". I recently saw my first 103" plasma when picking my friend up from his work, and if it was two years ago, my jaw would've dropped. But, I knew even that wouldn't be big enough for me today.
