	In my experience, the "barrier" presented by a twin rig has ONLY to do with
the presentation of full-frame 35 mm slides.  There are no readily available
mounts, as far as I have been able to determine, to make such slides easily
showable.  But they can be seen in the relatively inexpensive 2x2x2 Franka
viewer sold by Reel 3D, and they can be mounted side-by-side with a spacer for
projection in a TDC.  They can also be projected in two-projector setups.
I've done it all, and it works, even if inconveniently.  But where the twin
rig really shines is in the production of stereo view cards, using negative
film as the primary medium.  If you mount the cameras vertically, bottom-to-
bottom, you get pretty good lens separation for distances of seven feet or
more, and you get perfectly sized 3.5 inch wide prints that can be trimmed for
Holmes-type viewers.  If you mount them horizontally, you get a wider stereo
base, good for moderately hyper shots, and a great deal of latitude for
adjustment of the stereo window.   A twin rig is how I got started, and
believe me, I didn't experience any barrier as a result.

	So what do I use now?  It depends on what I want for a final product.  For
casual slide shooting, I use a Realist 2.8.  For stereo cards, I use the twin
rig.  For the limited amount of commercial shooting I've been doing lately,
where the film is going to be converted to VM reels, I run slide film through
the twin rig as my primary source (can't beat the resolution from the larger
format) and back up with slide film in my Realist, just in case the strobe
synch was off in the twin rig.

	If someone would produce a vertically oriented twin 35 mm mount, it would
make me VERY happy.
