Since you'll be getting 72 pictures off of a roll, I'd personally spring for Provia.
Let's say you shoot 10 images of a ISO 100 roll at ISO 100. Then, you decide to push the rest of the roll 2 stops to ISO 400. If you process the roll as ISO 100 film, the first ten images will turn out fine. The rest will be 2 stops underexposed.
The opposite is true if you push develop the roll at ISO 400 - the first ten images will be 2 stops overexposed, and the rest will be properly exposed.
Alternatively, you could go full mad-scientist and estimate by the number of sprocket holes where the latter edge of the 10th image is, then cut the film, develop that portion at ISO100, then reload your tank with the remaining film from the shot roll, and develop for ISO 400.
Pushing is a strange concept at first, but it is only shorthand for underexposing the film, then developing for longer to accommodate the underexposure.
