ASUKA darts' characteristics are first and foremost accurate well-balanced design of a dart barrel. In order to fly through the air, the tip of the object needs to keep the point upward against air resistence like often seen in jumbo jets and ski jumps. Therefore ASUKA recommends rear-gravitated that needs less throwing impact. Even the shape is torpede type, some adjustment is done to the threads to keep the center of gravity in rear. It is worth a try.
