Interesting article in the new Photo Techniques. They only tested 35 mm (and
not Tri-X 320), But found that:

there was almost no difference in dev times in the emulsions they compared -
old and new

Curve characteristics old and new were almost identical.

Biggest difference was grain - most emulsions were improved grain wise.
Especially Tri-X. The Exception was T-Max400, which was now MORE grainy. In
fact Tri-X had improved so much, it was now less grainy than T-Max400..

Testing was done by the ex-kodak product developers who developed Xtol and
other things.

Be interesting to see if this holds true for sheet film

BTW - they couldn't figure out where Kodak got there new, and sometimes
wildly different development times from.

Their advice was to stick with what you've always done for a said film, and
then see if there are any big differences.
