> stop using t-grain films(posted 8788 days ago)That's been my solution too, when possible. It's disgusting to have a dead-sharp 4x5 TMX neg that just doesn't show much apparent sharpness in a print.
Exceptions for me are Delta 100 (in D-76H 1:1 or 1:3) and Delta 3200 when I need more speed than pushed HP5+ can reasonably give.
Of course the usual rules apply; use a tripod, lock up the mirror if there is one, make sure the shutter speed's fast enough to arrest subject movement, use the slowest film feasible, don't grossly overexpose, make sure the enlarger's properly aligned etc.
