Incident is good for slide, or for any exposure-critical photo - or
should be. The interesting thing about wading through Roger Hicks'
book "Perfect Exposure" is that it leads you to think about which
part of the photo you are trying to sort out the exposure to - in
much the same way as the Zone System gets you to place your midtone.
Now, this might be obvious to everyone else reading this (someone is
I hope ;-)), but it is all part of my enjoyment of the hobby of
photography. Visualising your shot as you say Tom...
So, my understanding from the book so far (and I have got halfway
through this chapter) is that you cannot assume that your incident
reading is necessarily the "correct" one. The acceptance angle of
your incident meter is pretty important (invercones have a wider
angle than flat diffusers), as is of course the direction in which
you point the thing.
I have just taken some flash photos of carrier bags for my son's IT
project (website on carrier bags... don't ask ;-)) and I used
incident flash metering for the first time (OM2SP and T32 on half or
full manual and a Sekonic L308BII). The results are just what I
wanted and, although I used Fuji Superia 400 which has a pretty good
latitude, the exposure has worked on every single shot. This is with
a reflective subject with black background.

Incident is good for slides, if all the light is the same, or you move to
each variety of lighting in the scene (brightest, every shadow variation -
different things reflect into the shadows).
But that takes some time, especially in the mountains....
Technically (for negative films), you really just have to decide what you
want to register on the film given your film's top and bottom limits. So
spotmetering,if the spot is small enough, is ideal.
For slides, you want to previsualise what it will look like.

Absolutely correct description, Walt. I think that incident light readings
are almost always the best, if one has the time and the possibility. I use a
couple of Weston Master V with Invercone attachments when I can...
