Fot those considering it, I have used CT dev with Ilford CT paper and the effect is amazing. It gives an "icy cold" look that I found unique.
I could not achieve this look by any other means. If cool prints are your thing then do buy the CT dev and combine it with CT paper. If you are not sure but think it is a look that you will like then I don't believe you will be disappointed if you opt to buy.
I am not sure it was what I wanted but it really works well
