I am also a big believer in Tri-x. I like it better than almost all other black and white film.
I did, however, start shooting the Arista.edu Ultra 200 recently, and love it. It also helps that the bulk 100 foot rolls are 1/2 the cost of Tri-x. I was very skeptical at first, but I've shot about 20 rolls or so of the Arista.edu ultra film and have no complaints.
