I'm glad Herb Kanner has had good luck with XP1.  I know one other person
who thinks it's good stuff, too, and I respect his technical expertise
sufficiently that I'm sure it MUST be good stuff.

But it doesn't work at all for me.

I've shot it at 200, 400, and higher.  Higher is a disaster, despite Ilford's
claims.  At 400, it's far inferior to Tri-X.  At 200, it's far inferior to
Plus-X.  These results are based on my tests and a friend's independent
tests, accounting for around 100 feet of 35mm XP1 and small quantities of
120 format.

Incidentally, we also found that we got much better results in C41 
chemistry than with Ilford's XP1 chemsitry.  

I would describe the image as purplish, which sometimes has interesting
effects on variable-contrast papers....

And finally, since the image is a dye image, it's not a very permanent
medium.  If you are doing art photos, and are planning to destroy the
negative after some number of prints to guarantee a limitation to a
print run, this may be ok.  Personally, however, I want my negatives to
stick around a few hundred years.
