I shoot TMY 400 @ 200 and use Photographer's formulary TF-4 rapid fixer.
Fix for 6 minutes and agitate every 30 seconds. This stuff 'gets the red
No need for HCA.

  T-Max films like _vigorous_ agitation, none of that gentle
think-about-waving-it-around stuff. That doesn't mean more time, but more
action during the agitation period.

  T-grain type films (TMX, Delta, Acros) need longer fix times than
conventional films; four to six minutes (depending on temperature) in fresh
rapid fix with continuous agitation is fine. Also you'll need to use an HCA
to remove any leftover magenta color.

>All of the rolls I've developed have had poor shadow detail.

  Poor shadow detail is caused by underexposure of the film for the
developer used. For example, an ISO 400 film may need as low as EI 160 in
Microdol-X/Perceptol and as high as EI 640 in Microphen/DD-X. No matter
what the ISO rating is, you'll need to test to see what the real speed is
with your equipment and your developer.
