Back to the original question...
I have shot a fair amount of this in 2x3, 3x4, and 4x5. While Rodinal works well on it, it really shines when developed in W2D2+. It was if the expansion of zones 2,3,and4 were pressed into the film emulsion. What was solid shadow in Rodinal, broke into 3 distinct zones in the W2D2+. This was a test using both sides of a 3x4 film holder in a Zeiss Trona using exact same exposures, not more than 30 seconds apart. I had expected there to be changes in the upper zones of the film, not the bottom end. BTW, I meter and shoot at E.I. 160. For Rodinal, you might want to take it down 2/3s more (E.I. 100).
Don't get me wrong, you will get very printable negatives inRodinal 1+50 @ 68deg for 12/13 min.
