I am the original poster.
So, I finally got my camera and started with some testing. I am using FP4.

So far I have developed 2 sheets in Ilford DD-X and 2 sheets in Ilford Perceptol in SP-810 trays. I think Perceptol results are a bit punchier and DD-X is smoother more even.
I think I'll try Formulary's Pyrocat-HD next. I have the box but have not mixed it yet. I should probaly shoot exactly the same subject in the same light to compare developers.

These are extremely low resolution "scans"/photos just to get the idea of what the positive image might look like. I do not have a scanner.
