Someone, sooner or later will tell yoou to switch developers. It might as well be me. I can shoot TX in soup it in Diafine and get an easy EI of 1000, sometimes 1250. Diafine is a two-bath dev and that helps control contrast. There will be grain, but I don't find it harsh or overwhelming. Actually, using diafine gives me negs that really don't look pushed.
The above info is good, too.
Actually, if a change in materials were to be made Delta 3200 would be at the top of my list, may as well get a real speed bump.
