Digital BW, The Print

I am considering getting a second-hand 7600 and using it as a
dedicated black and white printer using a third party black and white
inkset such as the Peizography K7 or one the MIS inksets.

I've not used a 7600 before, is there any thing I should be concerned
with?  Should the ink cartridges be removed before transporting the
printer? Are there issues with clogging (with the pigmented b&w inks)
if it is not used on a daily basis, and if so are there any useful
strategies for dealing with this? I've used Peizotone inks with a CIS
in an 1160 in the past.  When it worked properly it produced
impressive output (unfortunately, it didn't work properly often)

Finally, does anyone have any preferences between the Peizography inks
and the MIS inks?  In your opinion, Does one seem to clog less, does
one produce better results?  Any differences in archival quality and
in attainable Dmax?  Does one supplier have a better performing cartridge?

Thanks for the input.
