I have shot some test rolls last year when the film was released and developed them in Cube XS, a developer offered by Laborpartner (distributed by MACO, too) especially for that film. The film does contain two emulsion layers. One low-speed fined grained and a coarser grained high-speed layer. Development times are quite long with any developer. Inconvenient for manual agitation, IMO. The film base is clear and gray-blue. The base looks like those of x-ray films. The prints do have a certain characteristic (hard to describe). They are sharp and have medium (and sharp) grain. I found out that it couldn’t replace any of my standard films. However, you should try a few rolls and form your own opinion.
