A curved screen is going to help correct the distortion from your anamorphic lens. As the horizontal stretch anamorphic lens makes the projected image smaller in the middle and taller on the ends, the curved screen reverses that.
Also, the concave shape of a curved screen helps keep the reflected light off the side walls by directing it towards the center of the audience. Light reflecting off the side walls can reflect back on the screen and wash the image out. Also, light reflecting off the side walls can reflect the color of the walls onto the screen causing the screen to color shift.
Screen size with your Runco depends on what you want for Foot Lamperts and also depends on if your room is totally light controlled, how big the room is, seating arrangement, etc.
Some food for thought....
Recently a video test was performed by a third party in a commercial cinema with the SmX CineWeave up against a recently installed 40 foot wide 1.5 gain screen. The 40 foot screen was split in half with the CineWeave on one side and the 1.5 gain screen on the other.
The 1.5 gain screen was producing 10.5 Foot Lamperts while the SmX CineWeave was producing 10.0 Foot Lamperts. It was reported that the SmX CineWeave had a much better viewing cone, color, contrast, sharpness and uniformity over the 1.5 gain screen. The brightness was pretty much the same.
