Whilst I use a curved screen, I agree that they are not always needed. A-Lens pending, the image can be made to look as good (both H and V lines brought into focus at the same time) on both a flat and curved screen.
If your going to use a curved screen, then the radius should match to actually offset the curvature of the pincushion it is correcting. Mine is thread adjusted, so can tailors to perfectly match.
Now that I have a curved AT screen, I doubt I would ever go back to a flat screen as I don't find the curve distracting at all, have corner to corner focus and perfect geometry.
I love my Constant Image Height system!
