I have a very minimalistic darkroom setup, so no matter what results are at least somewhat different from roll to roll. I was under the impression that stand developing might yield some better results in regards to tightening up some grain--which is actually my primary concern, moreso than contrast. Let me clarify by saying that there is MUCH more grain in my HP5+ negatives than my Tri-X.

For whatever reason, when I push my Tri-X to 1600, the grain almost disappears and I'm left with a wonderfully clear image--which is what I would like to try and achieve with HP5+ here's a picture of what I've already produced with HP5+ and a Rodinal 1:50 concentration:
