Which dual crystal should I go for

Zipio

So I was originally going to go for the mutant crystal because I want nick for the cmm synergy and to dupe my omega. But then the more I think about it the more torn I am with the science one as I wasnt doom and to dupe my cap iw. I'm currently on 6.1.2 so what crystal would bas better champs to help my get through that.
