Thanks for the link. I read it but it does not answer the basic question of the smaller the # the smaller the grain, or visa versa? I know with fishing, the larger the #, the smaller the hook so I am just looking for a clarification.

The reason I am going through all this is because I am down to my last 20 sheets of old TRI-X and I am faced with the dilemma of testing out the new and it is driving me crazy! I hate it when Kodak changes things!

I have been a TRI-X/HC110 man for years and I know how to work it.

I am also considering other developers such as XTOL and MICRODOL-X with the new TRI-X.
