Hey, if you get a tip from BMX, will you PM me? Thanks.
Yeah, I agree, you have nice gear.
I am a dummie, and didn't read into Cinetension.
If* you don't mind putting the screen up and down, I'm sure there's got to be a way to make it easier. You can even make your own screen if it makes having the right hooks/attachments easier to implement.
The Dalite HP material's waves are very hard to perceive as a pulldown, and in that size, my guess is $200ish. Some would say the waving is impossible to see, and while I disagree, most movies you would never notice a single waving scene. That's after years of ownership.
However, at this smaller size, it may very well be too bright. And tab tensioned would be the best solution here, outside of cost, you're right.
