Curves in c++

Hello,
I have my blueprints prototypes using standard blueprint method as I currently migrating this code to c++
But one thing I not sure how to migrate is curves is this best left as blueprints or is there a way to deal with this in c++
or should I move them from blueprints into my plugin content folder as I trying improve performance of my game and making it easier to manage by using c++
