I've kept my eye on the HP also.  I think their blended neutral inks are  the best.  See the Aardenburg fade test results, summarized for the neutral inks at http://www.paulroark.com/BW-Info/HP-Neutral-AaI-80MLH.jpg  

Only 100% carbon can do better, though we don't have tests that are up to the 80 MLux-Hrs reported for the HP inks.  But, so far, 100% carbon seems to have the edge.  See http://www.paulroark.com/BW-Info/Carb-v-Blended-Neutral-20MLH.jpg

The lack of a good and affordable rip for the HP is a problem.

Also, for B&W, all of the other 12 inks is overkill. 

The HP uses a thermal head.  We have no third party B&W inks that are made for this use.  It requires a lower viscosity ink and different base.  I would not recommend tring MIS or other Epson compatible inks in it.

I also consider my ink costs.  On that front, the HP, nor any other approach, can touch what I do.

So, my solution is to use Eboni and HP, along with dilutions of each, in a 7800.  It's working just fine.  See http://www.paulroark.com/BW-Info/7800-EbHP.pdf
