Digital BW, The Print

How neutral can you get your B&W images with the Epson 2200 printer 
and Premium Lustre paper? 

I've been using the GreyBalancer software downloaded and translated 
from the Epson/France website. Several months ago, after a good deal 
of trial and error, I settled on a series of GB settings that got me 
semi-neutral, albeit slightly greenish black and white images on 
Premium Lustre paper. 

Now that I've had the printer awhile longer and have gained a more 
sensitive eye to the situation, I'd like to fine tune my GB settings 
to get a more neutral image. My problem is this issue of so-called 
metamerism. I look at the images under varying light conditions, and 
the tonalty changes all over the map. Under incandescent lighting, 
the images seem warm or even reddish, and under daylight they take on 
a greenish tinge. Since my prints are going to be viewed in doors, I 
decided to calibrate under incandenscent lighting, but even with 
that, I can't get them really neutral.

What kind of results have you folks had with this 
printer/software/paper combo?
