Emma,
Just curious why you would want to switch to the Ana? For the extra 2 strings? Do you like her harp better (more comfortable, sounds better, closer to pedal tension)? If it is for the extra strings alone, it is a lot of hassle, and probably won’t make much difference in your repertoire. If it is other factors, that may be a different story.
You should also consider the greater difficulty in moving it around, but that depends on what you hope to do with your harp.
