Pretty cool tr6. I've had it in my plans to use the same remote curtain system exactly the way your using it.
I would have to mount mine to my soffit/ceiling above my screen, hopefully the track is pliable enough to follow the curve of my curved screen wall and therefore the screen.
Did you curve the track as close to your screen as possible, or does it go straight across? If I remember the back of your screen and wall are flat
Can you also tell me what is the thickness of the hardware (up and down)? I had to mount my screen higher than I initially thought so I don't have much space (about an inch or so) above my screen's border. I don't mind covering some of my screens border at the top because it is about 3.5" thick but I don't want to cover to much if I go with this.
Don't be shy about posting some pics of the new look
