Digital BW, The Print

I have been printing with an Epson 2200 for over a year, and have used
the supplied profiles from Epson for color with excellent results -
both Enhanced Matte and Prem Luster papers. But B&W was not
satisfactory,so  I didn't do any of this until I recently discovered -
via the commentary on this group - QTR. I am delighted with this
approach and find it easy to use. Thanks to the group members for
their comments. 
I have to question the necessity of doing all the work on developing
custom profiles when the out of the box ones do such a good job for
me. Its possible I'm not discriminating enough. I like music and have
a high end system, but I'm skeptical  when an enthusiast claims that
he/she can hear the difference between different power cords
connecting the amplifier to the wall. 
I ran a grid of B&W prints using the Harrington profiles in QTR and
they essentially do what the descriptions say:  warm, cool, 50% warm -
50% cool, etc. Why bother to develop new profiles for
paper/ink/printer combinations that are already profiled? Its more fun
to make pictures.
