Digital BW, The Print

Hi,
I'm going to buy ut7 inkset for my 7600, and I have a few questions:
Is the quality on glossy paper similar to the one is reached by ut3D inkset (no bronzing, good 
dmax, etc -> is glossy optimizer used ?)
If I'm not wrong I'd have to switch between mk and pk to print on matte/glossy paper, is it 
good to use the black channel for sepia/cool toner so I can use both pk and mk together and 
switch only when I need a different toning?
Lastly, the 6 (7 with pk) black used are 100%carbon or they are neutralized/toned ? I need to 
know it, because of ink separation on large format printer, and cause I'd like to work with qtr 
and use 6 black and one toner to create profile, without having to consider partially toned 
inks, that are harder for me to profile.

thx a lot
