I assume if you used the fullresolution images you have an original which is
around 4000x8000. It will probably make a great pano if you make a cubic
with 1500x1500 from that . The size with 50% compression will probably be
between 1,3-2 mb which is good .
If you want a preview I would use Quicktime Pro to make it . BlackandWhite
with blurr looks best I think but it is all a matter of taste.
RealViz and CubicConverter makes very ugly previews and I actually prefer
the black matrix instead. Many people find that real cool.

Sounds interesting . What is the FOV you got.
If you used Panotools to defish you could easy stitch a 120 degree FOV
Why not expand that to cubic. The upshot should cover the top and is easy
added in CubicConverter. It will even convert the Cylindric automatically to
spherical.
I have not understood why I have not seen anyone using this way.
You can actually stitch 160 degree FOV cylindrics with QTVRAS.
'You need the extra update if you stitch more than 130.

What about banding in the QTVRAS version. Read Erik Goetzes recent struggle.
