Funnily enough, I have been printing a fair bit recently and have made this choice for a few negatives.
I use an Omega D6 with an Ilford Multigrade 400 head - a diffusion source.
The glassless negative holders are aluminum - painted black on the bottom piece, and white on the top.
The attached example was shot in an RB67 - TMY-2 developed as an experiment in Pyrocat (PMK).
I like the aesthetic for certain photographs, including the sense of three dimensionality it gives to the result of the process.
Unfortunately, the APUG re-sizer seems to defeat my efforts to upload a sharp version of this scanned print.
