Thanks so much, everyone. I really appreciate all the help. I would certainly lean towards developing in D76, if I shot often enough to make use of the solution--which is why I think one-shot and liquid type developers are best for my purposes.

I've ordered some HC-110 as I've seen a lot of results on Flickr that I absolutely love using it. The below is a perfect example of the exact range and tone I would love to achieve from my Tri-X or any b/w shots.

Now all I have to do is figure out a way to get rid of the absolutely HORRIBLE curl I get from my Tri-X negatives! Maybe I'll check out Neopan 400 in the future.
