If it is anything like the Omega D5500 mixing box, you expect to gain about one stop (mine measures right between 1.5 and 1.333 stops brighter). So, you should be able to figure if cutting your printing times in half is worth it. I think so. A minute is a long time for an exposure but 20-30 sec is just right.
My darkroom is not finished so can't do any printing, but I did set the timer on the enlarger for 60 seconds, it did seem a very long time for a print exposure, I would not like that. Thanks for the input.
