With a big variation in PE rating versus breaking strain, why do the rod manufactures sell rods with a PE rating ? shouldnt it be an breakin strain ? I notice on the better quality rods they quote KG's at different angles. I use a Hearty rise jig force PE 1.5-3 quite alot what max breaking strain should i put through that ?
