Well, as the thread was about 120, I figured 120 is the format in question; I personally wouldn't recommend Rodinal stand for 35mm... but that's because I don't shoot 35mm. When it comes to 120, I'm fine with Rodinal stand with any B&W film I use. Granted, the highest speed i'll usually shoot is TriX 400.

Here's a TriX 320 shot freshly dev'd in Rodinal semi-stand (1:100, 1hr)

This is a straight-up scan with my V700 @ 2400dpi, no noise/grain reduction etc., and no PP.
