    Thank you both.
    I think I'll go with the second option, seems more convinient to implement.

    Yes, I read online and in order to overload asignment operator of pointers I'll need to wrap my class (it does make some sense). However, I think it is better to use it as a method (replacing '='...

    Yeah I guess it's better, I'll have to make some modifications later.
