I use this film once a week for my horse racing photographs - I like it a lot, but I would hardly call the grain structure "minute". The grain is there, for sure, but it is not objectionable.
I must add though, I scan the film and print on a lightjet printer. I sometimes use a noise reduction program to remove the grain, especially on big prints.
Why don't you buy a roll and shoot it as a test to see if you like it? That's the only way you work out if it will be suitable for your needs.
