Tom, that's interesting. Just this evening I printed from 35mm TMY (the previous incarnation of the film). The film was processed in Xtol (stock, replenished), to a slightly high contrast, so I had to print at Grade 1 using Ilford MGWT and LPD (replenished).
I got some pretty nice 6x8" prints from it that surprised me. I knew TMY-2 was fine grained, as I've used it many times in 120. But from 35mm I got prints that were sharp and almost grain free. A very pleasant surprise. I actually processed one roll in Rodinal too, just for fun, and was surprised by how tight the grain was in that developer as well.
Tmax 400 (TMY-2) is astonishing film, and will yield grain that you would probably find more in films like FP4+ or Plus-X. And, in Xtol, it's not a problem to shoot the film at EI 400 so the speed benefit can be retained.
