I try to edit dialog on inhales, or on esses. The most difficult edits are on
or around plosives, in my experience. And I do use pitch/time shifting when
editing dialog in certain cases, to make the vocal pitch match the emotion of
the sentence the edit is in.

I used the example of a banjo as one particular instrument where edits in mid-
note tend to be easier than edits at the attack of the note; of course, edits
in spaces are the easiest on most instruments, but the banjo is somewhat
unique in its sustained tone resonance.

I don't remember the exact year, but I was doing edits in CoolEdit Pro,
purchased with an Event/Echo Layla (that dates it pretty well, though), back
when it was still a Syntrillium product, and the edits were crossfades rather
than cuts. Even deletions involved crossfades rather than hard cuts. I don't
know what year you did the work you mention, though.
And it's a great idea to do those crossfades, because it is very tricky to do
a truly inaudible cut. Even with tape; I remember well the splice block we
used for two-track editing; looked more like a mitre saw box than a splice
block, as diagonal splices perform a nice crossfade on a single track, or even
on two tracks. Not of course doable for more than that, though.... we even
had a pair of Ampex single tracks with built-in splice blocks for that
I always considered zero crossing detection as a 'get me close' operation, at
least in Audition or Audacity. And nearly 99% of the time, with the material
I was editing, the automatic zero crossing detection produced an inaudible
edit without me having to go more detailed.
But I've only been editing my radio broadcast for 6 years now (well, 6 years
June 12th), and editing/producing spots, promos, and heads/tails on songs for
rotation for radio broadcast for the 12 years prior to that (we went all
digital at this radio station in September of 1991; the editing capabilities
of The Management's Digital DJ (later acquired by Scott Studios, IIRC) were
very rudimentary, and CoolEdit was a huge step up for us when we got it a few
years later). The 6 years worth of radio broadcast totals right at 150 hours
of material edited; not a lot, but something.
Having said all that, I don't miss zero crossing detection in Ardour, thanks
to the powerfully configurable crossfade capabilities.
