I agree that there are a number of variables.

First, the original VM inkset is obsolete, in my view.

However, one reason I like the variable-tone inksets, in general, is that I
can better profile papers to offset the tendency of many papers to print
rather differently in the shadows.  On the other hand, if I want cooler
shadows, I can do that also.

That is probably also true.  Unlike the early formulas, the UT2 and newer
inksets, including the latest UT-FSN, the darker inks or toners have a
different mix of "blue" toner in them than the lighter ones.  My ink
formulas have definitely become more complex (much to MIS's chagrin).

(The UT1 bulk ink has been updated with the latest pigs, but the dark and
light toners still have the same hue.  Users of the new inks may notice less
magenta in the shadows even with the single-hue new inks, however, due to
better characteristics of the new pigments.)

>That's the point where I think it to be "best" - aesthetically.

Of course, what each of us thinks is the "best" will vary.  I largely design
to my own tastes, but others clearly have other preferences.  

Part of me wants to make a pigmented low gamut inkset.  (With the latest
color pigments that I'm able to use, my desire to have pure carbon available
for longevity purposes has been virtually eliminated.)  A low gamut inkset
would be especially attractive to me if we could plug into the existing
profiling software.  However, at least one expert doesn't think they'll work
with low gamut inks -- a proposition I'd like to test.  Of course, balancing
gamut with metamerism would be part of the challenge.  But, if I could make
a low gamut inkset that had excellent monitor matching, then users would
have the freedom to custom design custom hues.  (Anyway, it would be a fun
challenge.)
