Tri-X in XTOL 1+3 is also very good and maybe more economical for you as well, as long as you can fit the required 100ml of stock solution into your tank at that dilution. The starting numbers I used were lifted straight from "The Massive Dev Chart". I've made some slight up and down adjustments to compensate a bit for different lighting conditions, but these nubmers work well as a start. Your own personal time will of course be yours. Don't worry too much, in fact not at all, about the two different designations for Tri-X. Some of the numbers reflect development times for the previous formulation of this film. In practice, the numbers are so close as to be insignificant.
