I am curious what type of viewing devise you are planning to use for a
pair of 6x17 images. An over/under viewer such as the ViewMagic would
work, but would not do justice. Verticals may be interesting and could
be viewed more easily.
I have had great success with a pair of Horizon 202's on a bar with a
double cable release. Then mounting the images in panoramic mounts for
medium format viewers. The swinging lens doesn't appear to create any
uncomfortable viewing situation except for when I tried to do close-ups
of a few feet distance (using a home-made +1 close-up lens). In that
case I used a single camera on a slide bar. The images were fine in the
center, but were distorted on the sides. My theory is that the camera is
swinging into the scene rather than parallel to it. It would be like
placing one camera behind and to the side of the other.
