IMO, Developing by inspection is absolutely the way to go. You can use any developer you want, preferably one you are familiar with. You'll be able to develop more than one at a time this way as well. I would practice with a couple of test negs first. You can start checking at N- times and watch it until it's done. I've never DBI'd Tri-x, but I don't believe there is a problem seeing it, unlike TMY.
