Yeah, I moved away from Rodinal for a while when I found myself shooting Tri-X, HP5+ and Fomapan 400 exclusively. Going back to anything rated 100 ISO and lower really shows off what Rodinal can do, and the resulting negatives are more pleasing (to me) than anything I ever got from something like Tri-X, regardless of the developer.@Coldkennels you basically explained all the reasons why I stopped using Rodinal. With fast films results are grainy (even more so if underexposed) and terrible streaks when i did stand developing. Also, I found that i had to expose Tri-x to 250asa to get a good negative. Never used it with slow films thought. Apparently slow films are its remit.
That said, the one fast film that Rodinal REALLY worked with was Ilford's Surveillance P3, which hasn't been made for quite some time, so I didn't include it in the earlier post. That, oddly, looked at its best with a one or two stop push from 400 ISO to 800 or 1600 ISO in Rodinal 1:50. I shot something like 450ft of that stuff in the early 2010s and never found another developer that made it shine like Rodinal did, and I've never understood why.
This is a terrible scan from when I only had a flatbed to hand, but the finished 8x10 print on RC multigrade paper was fantastic:

I wish I could still get hold of Surveillance P3. The film base was annoyingly thin, but it was a joy to shoot and print once I got it dialled in.
