I shoot Tri-X at 1600 and 3200 more often than I shoot it at 400 or 200.
A lot more often. I like to use straight D-76, or straight Acufine, or DD-X 1:9, with lots of agitation.
For even more fun I use a Red 25 on my lens (either a 35/1.4, 50/1.4, 85/1.4, or 105/1.8)
It's an acquired taste. You've been warned.
