While vertical misalignment may not be a problem with the RBT, it is
definitely a risk when shooting with twin camera rigs.  Slight film
misalignments in the camera, or in the mounting, can cause major
problems.  I have many 2x2 twin rig pairs which I'd love to remount
someday just to cure this problem.  I've had to raise one slide or the
other by hand slightly when viewing to correct these problems.
