Actually Both T-Max and Tri-X are monodisperse emulsions that have 3 layers that serve as fast, medium and slow components of a single film.
The difference between then is that the 'old tech films' use cubic crystalline forms, and T-Max use Tabular grains.
According to Kodak T-Max have a -2/+3 latitude the old emulsions have -1/+3.
I think the last polydisperse(irregular) film from Kodak was Verichrome Pan
