hmm, a nap makes everything a little bit clearer
Thanks for the replies!!

I don't plan to use the films for duplicating, I'm looking for something that will be inexpensive to pump through the camera in volume and have an interesting look to it.

My biggest concern is getting enough speed since I'm primarily looking for a film I can use handheld.

The film I could find the least data on is: 2421 AEROGRAPHIC Duplicating 2421 (ESTAR Base) (b/w).

A 19th (turn of the century) look might be really cool!

I'm not opposed to ordering a 100' of tri-x. I'd never really thought of using oddball films before and the idea rather appeals to me.
