Congrats - wish I had remembered you had it before I ordered some recently, but I have an unopened bottle I'm not sure I'll like anyway, so I wasn't going to go for this.
I jump around a bit, but really just T-Max and D76 with Diafine for its special magic. I like Diafine for Tri-X in low light that isn't so low it demands TMZ or Delta 3200, and for taming highlight contrast in some light, or with Pan F+. That makes a great combination when EI 64 will do, but that's not much of my shooting.
I just wanted to try HC110 while I still could.
Trying to talk myself into spending the money for a box of 4x5 TXP too, since Ansel and many others have loved that combo. I'm getting toward the end of my stock of TMY-2 and Kodak sheet film is so much more expensive than Ilford I'm very tempted to just move to all Ilford (and some occasional Foma just for fun.)
