Six shades of gray ink does not offer an advantage over four. The Piezotone
system for instance uses only 4 inks (1 black and 3 grays) in the six
channel printers doubling up the two darker grays.

What can help you by using a 6-color printer is the total number of nozzles
available for printing. Practically the difference is probably negligible
though.

Your biggest problem is that there are no software/workflows for either the
750 or the 760. Unless you are prepared to do a lot of work developing
curves to work with these printers, I would recommend that you use a
different model for dedicated B&W.
