Richard,
You must have something very unusual in your VDB mix. I have mixed
the stuff with many different batches of chemistry from several
sources and it has always given me a paper that needs a very high
contrast negative, upwards of log 1.9. There is absolutely no way I
would be able to print a negative with VDB that prints well on a
silver paper. At least not if the goal was to print both ends of the
scale.
