Digital BW, The Print

I'm interested in converting a used Epson 4800 printer to a dedicated 
B&W printer (using no K3 inks).  My goal is to produce prints that 
match (as close as possible) to the WARM NEUTRAL tones you see in 
Lenswork magazine.  Lenswork uses a Black color and a Warm Gray color 
for their duotones.

I was told this is the forum to go to for the answers.  My research 
have produced a short list of things to consider for the switchover.  
Can anyone give me THEIR take on which...

1.  inks to use?  (MIS UT-3D vs. Piezography K7 Split Tone)

2.  RIPs to use?  (Bowhaus IJC/OPM vs. Quadtone RIP vs. Ergosoft 
StudioPrint vs. Colorbyte Imageprint)

3.  spectrophotometer to use?  (EyeOne - not sure which model vs. 
Printfix Pro v2.0)

4.  matte/glossy papers to use?  (Hahnemuhle Fine Art Baryta, 
Hahnemuhle Fine Art Pearl, Moab Colorado Fiber Satine, Intelicoat 
Magiclee Siena, Epson Exhibition Fiber, Harman FB AL Gloss, Pictorico 
White Film, Epson Ultrasmooth Fine Art, Inova FibaPrint, Museo Crane 
Silver Rag) - which papers/finishes works best under which situations?

Please elaborate on your recommendations by discussing some of the 
issues, pros & cons, good/bad experiences, tradeoffs, and why get one 
over another?

I would like to figure out the best ink/RIP combination to use based 
on people's recommendations.  I also want to settle on no more than a 
couple of matte and a couple of glossy papers to use.  Too time 
consuming and too expensive to flip-flop between all the different 
papers out there.

Thanks.
