The O.P wants to use the film in a controlled studio environment with strobes, extreme latitude is unnecessary because the light is measurable with a flash meter and under control, indeed 160 I.S.O. can be a problem in small rooms if you cant turn the strobe power down enough. I've used Portra 160 extensively for studio portraiture both in 135 and 120 and the fineness of grain, latitude, and natural skin tone rendition are perfect for the purpose, and I have no problem getting from my local pro lab. 20"X16" prints even from 35mm negatives.

I do have a stock of Portra 400 in 135 and 120 in my freezer, but I save it for marginal lighting conditions when I really need it.
