>I was thinking about (planning to) shooting a 3D movie and I was
wondering if I should use a 60 to 70 mm stereo base all the time or
use the 1 in 30 rule and readjust the stereo base for each shot.  Does
any body have knowledge or experience in this area?  If you do, I
would be very greatful.<

My own approach would be to adjust the base within reason for each shot,
because I would want to try and keep the main focus of attention near the
stereo window. I think a lot of the "eye strain" that some people associate
with 3D movies comes from sudden and frequent shifts in the apparent
position of the focus of attention, especially when the "apparnet" focus
(where the subject APPEARS to be in space) is radically different than the
"actual" focus (the screen plane).
