Agreed.

That's the formula I think is real close to ideal, and, in fact, close to
where my 220 is headed next. 

If you're into glossy printing with Glop, you could interchange blacks and
have Glop in the Y position as an alternative to the PKN.  In another
alternative that is being set up by a B&W Print forum member, sepia is going
into the Y position (or a 1280 -- they're all close to the same).

MIS R2 can be set up that way.  Frankly, standard Eboni-Lk-LLK for the warm
& MK, with a neutral gray set makes a nice combo (R2 or a UT14 derivative --
or the HP PK and greys I've been experimenting with for the high end or
where ink separation may be a problem).  With the HP greys (they spell it
with an "e") one can use either OEM LK and LLK, or mix them down from the HP
PK with my standard C6 base.  When one dilutes the HP greys this way, they
are cheaper than even third party bulk inks, and they may be the most stable
neutral gray inks -- very high tech stuff.
