I've taken HP5+ in 120 up as far as EI 12800 with the developer Donald Qualls calls "Super Soup"; I posted the results in the thread at (there was a url link here which no longer exists) . I've gotten results I liked with it using Tri-X as well, but never with careful metering to know what EI I was shooting at---circa 3200-6400. At 12800 the shots with HP5+ were pretty darn grainy, but not worthless (though they probably would have been in 35mm).
I've also done some experiments with pushing Tri-X to 3200 with different developers and techniques. The main thing I learned is that stand development in HC-110 doesn't work too well...but a push of this magnitude in PC-TEA (similar to Xtol 1+2 in its mix of developing agents) can look surprisingly good. I think it's about a tossup, to my eye, between Delta 3200@3200 (HC-110) and Tri-X@3200 (PC-TEA).
But if I were you, I'd do some experiments with this "Super Soup" stuff and see what you think.
