Digital BW, The Print

After 5 years of printing with a 1160 is time for me to change my 
system.
I just find a good epson 2100 on ebay and now I'm starting to look 
for a new inkset for this printer.
Still today I used the Mis FS-N with the piezography plug-in and CFS. 
I was very happy of my results... but the 1160 is near to the end.
I don't need the sepia or cool tone so i'm looking for an inkset that 
will give me the best results with a neutral tone.
I'll like the possibility to print also on glossy paper.
On the web I see the only the new piezography k7 is realised for a 
simple neutral tone. Mis proposals are only for variable tone inkset.
In these years I had no problems with Mis so I'm trying to understand 
if I can find a good solution on mis products.
My question is: can I see the difference from a print realised with a 
dedicated neutral inkset to a print realised with a variable tone 
inkset on neutral tone?

Thank you
