OK, quick question about my options:

If I opt for a color head,

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?

I, however, did the same thing. That is, I devised a large Cokin style under-the-lens filter holder to fit my 300mm lens, then gave that up for a dichroic head. However, the reason had nothing to do with the filters. It was that my coldlight head was uneven.
