My Tri-X speeds on sheet film ranged from 25 on up, depending on what developing time I thought was right (N-3 and so forth). On 35mm I used 200. Marty is right about gloves. I have read that analine dyes are used as a solvent in "normal" b&w developers (one of suspects in kidney cancer). I would never mix pyro from powder. Gloves are recommended with the other solutions also, e.g., dissolved silver in the fixer and so forth.
