Some people used to use HC110 replenisher as a developer for pushing Tri-X to very fast speeds. You can find some info on this with a Google search. This is less popular now (was never that well known) that films like TMZ and Delta 3200 are available, though I wonder what it could do with them. I don't know if the Freestyle Legacy Pro brand would work for this; they do make replenisher. I'm tempted to give it a try. One formula I found was to use HC110 replenisher at 1+15, for 5.75 minutes at 75F, for an EI of 5000 with Tri-X.
