You have to choose between getting decent highlights or decent shadows in that case; can't have both. The alternative is to switch to the New Cyanotype process of Dr. Ware, which requires very contrasty negatives (and prints much faster). It's also more sensitive to the paper used and any contaminants. In my experience, cyanotypes (classic or new) have no good means of contrast control, in the sense of accommodating for a range of negative contrasts (you can increase the dmax of the print by using a quite acidic first wash; the acid used subtly affects the tone of the print). Classic cyanotype is in my experience vastly more forgiving and robust and works very well with digitally printed negatives since they don't require so much contrast in the negative.
