I'm not an expert with nunchaku, but I'd tend to agree with this from my experience. If they stay in one hand, you are lmited at each moment as to which targets are available. If, at the end of a movement/attack, you have the option of changing hands, you have some new targets and directions of striking available. It seems to me that the nature of the nunchaku make switching hands advantageous, assuming there's no kali stick in the other.I'm going to disagree. The ability to switch hands (especially when setting up strikes) is a huge strength of the nunchaku as you move it around your body.
