Paul,
Those Plustek holders for the OF120 are very well made, solid, so should be fine. But if the film has curvature they will not necessarily hold it completely flat. You may wish to try simply placing the film on top of the glass face of your duplicator, held down by a piece of TruVue Museum Glass. I have done this successfully without encountering Newton's rings.

Thanks to all for your input. As far as wet drum scanning is concerned, on a Tango for instance, which would provide the highest quality standard, I am aware that this is the sound way to do it. I have to skip for financial criteria. The digital camera way is cheap because I have it, and I also have a speedlight slide duplicator that only requires a small adaptation to accept the Sony body. I need to purchase a film holder for 6x7 and 6x12, and am considering a Plustek holder for the OpticFilm 120, in case someone knows it and can confirm that it is a good choice (flat surface on the bottom, to rest on the glass?)
For the file size, two shots stitched provide enough pixels for most of what I do (16" @300 dpi on the narrow side). And I can also turn the camera perpendicular and slice more into the film for the ones I intend to enlarge more.
I am not far from being able to carry some tests and comparisons, camera vs Eversmart, which btw is HCT calibrated. But what I still wonder is what gain will I get with the camera from a film source (mostly Velvia), which is not a real life scene. Does film offer a wide gamut intrinsically? Where would a piece of Velvia stand, for instance say between sRGB and ProPhoto RGB? Of course there is more than gamut and the extended D range and bit is also to be considered.
Best regards
