Beter control of contrast. I could not do 00 or 5+. The results were good with the color head but I liked the filters beter. I sold the head when my sons started useing the darkroom. I wanted to just start them on filters.

I also had some problems doing split printing. I would move the head when I went from grade 0 to grade 5.

This was my first enlarger. I bought it in 1976 and my kids are still useing it.
