JP-Pro guide keel has serious advantages over traditional Leitkielen. Round the shaft is slightly tilted back so that the guide keel if correctly mounted front is a little upward This "burning" of the grinder from behind to the front and the friction on the strand is less. The second major advantage is the guide keel-sword. It is wider at the bottom, so that only one edge is located at the slot and not the entire side surface. Moreover, the sword is very long for a smooth run in lane slot.
