I've just developed a bunch of TMY2 in xtol 1+1 and man is this stuff nice. I cannot believe the detail. Of course I am using my Hasselblad 905 SWC which certainly helps, but this stuff is really nice.
Well, I don't use xtol but I do like the TMY-2 a lot. It is pretty impressive in all formats. I think I would be pretty excited by most anything coming from a SWC, those are pretty cool too.
I had the same feeling with some initial test runs with the combo. Some limited printing so far shows that I need to sort out some minor issues but I think it will be a good, predictable combination. Really amazing detail, as you found, too. I also found it very pleasing in 35mm but have mainly used it in 6X7 sized negatives.
TMY2 in Rodinal is my choice combo. In my mind, Rodinal is nice because it basically lasts forever and it is sharp (with gritty grain). TMY2 is nice because it is not 'too' grainy in Rodinal - 35mm to 8X10 is quite accpetable.
