Mike,(posted 8391 days ago)Special formulations that promise to keep grain under control, usually steal one or two stops of film speed. So using a 100 ISO emulsion can be the best solution, right from the start. If the subject permits, take a tripod and go ahead. Or, as stated above, try some larger format. C-41 films look great, if you can make decent prints from them. Good luck.
