Tri-X is great in Diafine at 1000-1250 but not at 2500. At that speed I second the suggestion of Delta 3200 (or TMZ which is still available from remaining stock but if you change you might as well change to something still being made.) I get superb results from D3200 at 3200 in T-Max developer and I'd think D76 wouldn't do too badly at 2500.

But the OP is just seeing the inevitable results of the way he is using this particular combination then asking how to escape those results without changing materials. Sorry, TANSTAAFL.
