That might depend a lot on the slide, and its importance. :-)
I can testify that multiple passes *do* reduce noise, and I've used up to 10
on really nasty problems (I just go watch television for awhile). But of
course, using a Scanwit, multi-scanning is one of my few options, and only
with Vuescan. :-)
Still and all, the Gausian Blur is also a very usable solution (best used
for isolated "noise" areas, I've found), and using the grain filter to
reintroduce texture is an excellent added idea.
Thank you, Charles, for adding your techniques to our "Problem Solving"
toolkit.

EIGHT passes?! Even if I was scanning just one slide, I doubt I would be
patient enough for that....
If I'm doing a slide for subsequent reproduction in print, I may gaussian
blur the darkest areas, then use Photoshop's grain filter to give them
texture comparable to the rest of the image. I figure that dot gain in the
printed version would lose most of the detail in the really dense areas
anyway; but if I left the noise uncorrected, some of it might be barely
visible.
Obviously this is NOT a preferred method of working! The two pix I sold
recently to Discover magazine (I emailed the scans to them) came out okay,
but still, I am looking forward to a scanner that doesn't create tracks
through shadows.
