Don,

Just for the record, I did not say that the Dmax of VDB sucks, only 
that I have never been able to get quite as much with it as with 
kallitype. However, if you set out to compare Dmax with the two it 
should be done with equal conditions, say single or double coating 
both on the same paper, same RH, etc.
