that is a tough question...since the color renovation and all. There is a great chart with copic comparisons to the SU colors
in this thread Post #35. You could compare the colors to what is in the sets and see if that is the way you want to go.
I personally don't like the 72 A, B, C sets because they don't have enough of 3 color combos in them that you need for optimal blending.
I found that starting out, it may be more beneficial and cost effective to make your own custom set.... you can do that at Period Style
and it will come with a case...or you can just order individually and log in create a profile on oozak.com
for the lowest price.
I have some info on my blog to help with picking colors and getting started...here
.... also check the copic certified instructors sites for their starter color recommendations too...
