I got to use a few sheets of Velour Black before it was discontinued. It was very nice, but there were also many nice papers from Kodak and Agfa at the time. For some reason, Ilford was not stocked in the area where I lived.
After the invention and popularity of RC paper, and with the Hunts manipulating the silver market (maybe an excuse, maybe a real reason) Dupont got out of the film and paper business and the other manufacturers began to cut back on their fiber based papers. I think the old, fondly remembered papers aquired an aura of mystery at that time as the quality of the new papers took a dip. That was a time Kodak, for instance, was experimenting with putting brightners in its paper emulsion.
The paper situation is much different - and better - now. I don't have any of my prints on Velour Black, but I do have some from the same period on Kodabromide, Medalist, Brovira, etc., and I don't see them as any better than the good modern papers.
I will say that, to me, all chloro-bromide papers have a weaker look than either the all chloride papers (Azo) or the all bromide papers (Kentmere Bromide). I don't know why that would be, except that a compromise is always a compromise.
