Digital BW, The Print

I just switched from UT to UT-7 inks, and I'm going 
through a, er, learning phase... meaning I have a lot 
of dumb questions. :-)

I mainly print on either EEM or H. Photo Rag. Using the
UT inks, I could basically use the same profile on either
paper (relinearized, of course) and get a very similar
result, despite the fact that Photo Rag base is more of a
cream color than EEM's brilliant white.

Now, with the UT-7 inks, I just printed a picture on 
Photo Rag, and instead of being more or less the same 
as on EEM, it has a strong greenish cast--very muddy 
looking grays, too, and darn ugly. I thought it looked 
a little off until I set it next to both a UT-7/EEM and 
a UT/Photo Rag, both of which look very nice in comparison.

I'm using a 2200 with clean nozzle checks + IJC/OPM.

Now, my questions, for anyone who knows both the
UT and UT-7's. 

(1) Have you been able to get more or less the same 
hues from either set? Or should my expectation be that
I've switched to a different "palette", and trying to 
match my old UT prints (or close) is misguided? Obviously,
the profiles will be different, since the component inks
are different, but I don't want to get into IJC profile 
tweaking if this ain't possible. (Actually, I have been 
messing with profiles, with zero success.)

(2) Has anyone seen this dramatic difference between EEM
and Photo Rag with UT-7?
