I use DD-X. Everything is 1:4 I believe.

Maybe it wasn't grain, but contrast. One of those two. I had issues with both at first, so tried a variety of techniques to quell both and clearly which one was for what got messed up in a jumble. I never said anything as far as 10 seconds a minute not giving me dark splotches. On the contrary, that first image with the splotches was developed using that very technique. I don't photograph serene landscapes that you can go back to exactly and re-photograph. I do street photography, which is constantly changing. I don't really have the means to waste two rolls of film, either.
