I personally think a condenser head is great for B&W.
Less things to go wrong vs. a color head with its power supply and internal filters, cams and gears. Especially if the manufacturer is out of the enlarger business, as is the case with Durst.
I've used VC filter all the time, and find them not to be a problem. The under lens setup the Bruce shows is even easier to use than dealing with a filter drawer.
Granted the color head is more convenient to just dial in the filtration.
