Since you're shooting 645, you could choose an ISO 400 film and shoot it at 200 or 250. Fine grain/slow film is no benefit (to me) when there is motion blur due to handholding at lower shutter speed than should have been. This is an idealistic goal of course. Fine grain with motion blur can be beautiful in some cases in the right hands.
