Rollo is less tricky than PMK but both have the same stain. I am a PMK User but as a trick for any way I develop.
In tank for 35mm and 120 it is really better when you agitate every 15 sec.
for 8X10 and other sheet film I develop then in small drum and do the same with great succes. I always dio the after treatment , but never do the long watr bath , my fim are already enough yellow green
