I once had a Leitz V35 with speed matched contrast steps. Later I got a LPL color head and found myself using under the lens filters or dialing in only megenta. If your negatives normally print within a one contrast grade spread, (2.5 to 3.5) just using magenta is easy.
I print test strips when changing contrast and the magenta only technique does not slow me down. I have learned instinctively when to add a second or two when increasing contrast. Megenta only allows you to avoid printing though higher density and avoid exposure times over 30s.
If you do complex manupulation or print balancing this will not be as convenient as dialing in speed matched contrast changes. Good negatives with simple techniques produce good results with less frustration. Its all in a properly exposed negative.
