It has been some years since I worked with color transparencies. A great deal depends on what you want to do with transparencies if you decide to use that film. Transparencies shine when used for projection and in color separations for printing.

This means that prints made from transparencies need to have one of two compensations at the printing stage to realize their true potential. The first would be contrast masking (that is what Chris Burkett does) the second would be to produce a color internegative and then using the color internegative as the basis for the print. I have seen excellent prints made both ways.
When I shot color transparencies, I did print with both types of Cibachrome and found that contrast masking was absolutely necessary.
