Glad to hear this.
I think what could hold back the Civa in the C-130 is the fact that you don't have two separate DME displays as the FO side only doubles the one from the Captain, showing you Nav1 related data on both sides.

This could be a problem when you e. g. want to cross check the Civa calculated DME values and compare them to the measured ones. Of course, this only is a problem if you run a double Civa CDU setup. The second CDU usually is bound to Nav2 there, so you could need a display then.
