The product number SP means "slow pitch jerk". A dedicated model with a high repulsion slow taper developed for slow pitch jerk. Blank-through structural specifications. Slim, high-resilience blanks with high elasticity base of 30t and 40t carbon elasticity. It is easy to fly the metal jig sideways easily, and it is possible to make the timing to let the fish eat it firmly. The design that makes it easy to operate the jig from fast movement to slow movement and the production of fall by intentionally changing the rod work and angle makes it easy to approach fish that did not use the mouth until now. A jig of around 200g is the easiest to operate, and is the best match for fields in the bay and in the near sea, regardless of whether it is shallow or deep sea! In the case of mid-deep sea where the water depth exceeds 300m, it is possible to cover jigs of around 350g. Berkley Fireline has a very low growth rate for this fishing method!
