Just curious about the current formulation of this film. How far back does it go? I know Tri-x has been around for quite a while, but not a lot more.

Update - well, I found this link - its a start, but for a film thats been around so long, it's more of a summary - http://en.wikipedia.org/wiki/Kodak_Tri-X

i've been using arista premium 400, which is tri-x, for the last six months or so pretty exclusively and i've been very impressed -- much nicer than the stuff I used in high school in the mid-60s, which was very grainy even on an 8 by 10 enlargement. I've got about 500 feet of it in the freezer and just ordered two bricks of the pre-loaded since, cost wise, it works out to a better deal to buy it already loaded. go figure.
