Digital BW, The Print

I would like to start with BW inkjet printing , and really didn`t like 
the tone of piezography ( prints I´ve been shown seemed kind of 
greenish  - this is probably just my own lack of taste ;-))

There is very little  input here about Lysons Small Gamut inks ..
I like the the color steering thing but I´m unsecure about the dot 
and tonal range ,,,

MIS variable seems promising , but I`m not sure 
if  pigment based ink will give me  deep blacks while 
printed on glossy paper ...
And I´m bit nervous  while reading some posts that MIS 
( I don`t know if this concerns also variable ink ) is even 
"greener" then Piezo . 
Mis variable cannot move along magenta - green axis ...

I like MIS price and  it is available ( i think )  for my spare printers 
( EX and 1200 ) .
Shall I start with it or should I go for SmallGamut  with 
a new 1160  ?
I would be greatfull for some suggestions .
Longevity is of lesser concern for me then tonal range .
( I work mostly  with commecial/editorial  stuff  )
