A dichroic head for split contrast printing? You are going to twist those knobs all the way back and forth twice for each exposure? Even on the systems with buttons, the lamp has to be on to make the change in many cases (though you could put the lens cap on). Maybe I missed something, but didn't you just post that you have been using under the lens filters with no problems and devised a holder for the bigger filters?
