I've considered picking up some 200 but I don't want to lose the stop if I don't have to. Most of my shooting is outdoors during the day but there is a mix of sun and shade here and there.
Historically the lower ISO films had smaller grain. The new film chemistrys are braking the old film speed and grain rules. I have shoot and developed many rolls of old gun camera out dated film, it was all ISO 400. I have had some very good photos, but many not so good photos.

The most costly Item is the developing tank if you going to do your own B&W developing.
