The negatives have a fine grain as well. MACO's and Konica's films are somewhere in between. Konica's film has fine grain but a very low sensitivity, making the usage of a tripod mandatory. Note that the tested rolls of MACO's IR 820c have pre-production status. Kodak's TSF SO-033 doesn't have enough red sensitivity to show a noticeable Wood effect.
All films have their applications.
Sometimes, choosing the right film is difficult. I often shoot them in parallel, with Ilford's and Konica's mostly in medium format, and decide about the 'right' choice while printing. Kodak's and MACO's films have to be loaded in total darkness and great care must be taken in using them to prevent fogging. Kodak's film has some additional idiosyncrasies.
