Digital BW, The Print

Hi I've decided to go ahead and buy an 1160 due to many reasons, including
affordability and they are very very easy to get in australia... So now the
printer part is settled, what MIS inks should I get (im planning to go
CFS)... Im thinking FS-N, because neutral B&W is probably more versatile for
me than having to fiddle with sepia options if I get VS-sepia (altho its
nice to be able to print sepia)... So my question is, considering i want to
print mainly neutral B&W, can VS-sepia achieve as neutral tones as FS-N
whilst allowing one to print sepia as well, or am i better off with FS-N
becos its neutrals are more superior than VS-sepia?
