I originally posted this reply to the person who wrote the original query,
but it came back as undeliverable.  So...

I use the Technical Pan almost exclusively for B&W now; not too long ago,
I experimented with using conventional developers with it.  They don't work
satisfactorily.  Levels of luminance that fall on the linear portion of
the characteristic curve turn out looking fine, but the parts out at the
ends end up washed-out.  The result looks like you simultaneously overexposed
and underexposed the photograph.

The Technidol works very well.  I wish, though, that I could find where to
get the chemical required to mix your own... I posted a query in here about
a month ago, you'll recall; but no response at all.  Technidol's not that
expensive, really, considering the improvement in quality.
