I never liked Rodinal at 1 to 50, except for high contrast situations, on the other hand I found 1+25 too contrasty except for very low contrast lighting, so instead for about 20 years I used Rodinal at 1 to 37.5 which is the same as 2 to 75 with superb results. That gave me negatives which were very deasy to print any way I wanted.
