I recommend the Dingo. From my experience, the Dingo is thinner than the Popstar, making it easier to fit into your pocket. Also, it is slightly smoother than the Popstar. (I feel a slight jerk in the string when throwing the Popstar, something that does not occur in the Dingo.) It may be due to the lack of friction caused by the k-pad. The only con is that the shape takes a little while to get used to, as it is not much of a butterfly shape.
