Yes - but I don't use chromogenic film, preferring the real stuff
which gives me much greater creative control.  I just experimented
with it to get a sense of what it could do.  However, I can see
where I might use it in a specific situation, but certainly not as a
general rule.

BTW, according to Kodak, Tri-X (and other conventional B&W Kodak
films) has enough latitude that it can be exposed one stop under and
processed normally.  So, it seems, it's possible then to shoot
several conventional B&W films at both 400 and 800 on the same roll
with "standard" processing.
