A lot depends on when film was made. Tri X has change elmultions several times over the years. But in manner you described of storage conditions, you may get 5 years after expiration date on package. I'd test a roll and see how it comes out, it may suprise you. Color iS a whole differant bag.

I have a half a brick of Tri-X that's been laying around for a few years. I know that with time and temperature, film loses speed and contrast. If kept unrefrigerated, at room temperature (along with slight seasonal variation), how long until it's not worth exposing?
