I think they serve slightly different markets.  The C6 user-mixed base is obviously the least expensive, and it's what I'd continue to use if printing only on matte paper. 

The Gloss Optimizer dilution base, however, allows glossy printing with vastly reduced reflective artifacts.  I think combining a truly fine art quality pigment with this relative lack of artifacts adds significantly to what is available to us.

It will for me.  There probably are still some papers that will show artifacts, but there are also papers that look very good with nothing more.  I'm definitely not a fan of sprays or running a print through a printer a second time for coating.

It's a fraction of the cost or the HP PK and it avoids the gloss differential at that end.  The HP PK is high gloss.  It's so dark by the time the MIS PK takes over that it's not an issue in terms of color or hue.  A less than 2 unit Lab B rise at 90% is not even visible to me.

I might add a note on costs.  The LK density inks cost is the equivalent to $32 per 4 oz. bottle when MIS glop is used as the dilution base.  The LLK ink is the equivalent of $20/4 oz. bottle.  The PK, of course, is MIS' usual $18/4 oz.  So, we're looking at an average of about $25/4 oz bottle in terms of comparing prices.  This is not a bad price for a neutral monotone pigment that is in a class by itself.  So, with MIS supplying about 80% of the volume of the final ink, the costs are held way down.  

I'll be adding material to the PDF at http://www.paulroark.com/BW-Info/1100-HpGO.pdf as I learn more.
