Sounds like it isn't too bad, and that there may be other lurking factors in action. Good for you for giving both films an equal opportunity to perform.
The bulk roll is OK. I exposed and developed two test rolls; one from the bulk roll and one factory packed Tri-X. I used a manual camera and both rolls came out identical in density and contrast.
It appears that my original roll from the bulk roll was somehow underexposed. It may have been the doctored DX code, not sure. Sorry to have troubled everyone with this.
