No reason to bother if you don't want to, but using the reason that you don't want to use flats because their response is different to what you are used to doesn't seem like a particulary helpful reason. In the same way we could say, why bother with another bass, why bother with a different amplifier, why bother trying different playing techinques, why bother with different music types etc as they would all be different to what you where used to. Perfectly reasonable if that is what you want, but seems an odd reason. Maybe some things could be better.
Not as good a reason as 'I don't want to'.
I mean, I don't really like flats, although I have them on one bass (a squier mustang) where they work, and where I also overshot at first, I don't now, its a different scale and a different type to the others, and I play it its way.
Its just habit and muscle memory
