SK-POP Grande tuned by Lake Biwa guide Naoya Hiramura. SK-POP Grande has been tuned to retain the horizontal floating and heavy bass POP sound, which are the biggest features of SK-POP Grande, and to have hook power that can drag big bass out of the cover. The hook is one rank larger and the wire diameter is thicker. Due to the use of a thick hook, the lure weight is increased and the floating posture becomes more sinking than the conventional SK-POP Grande. I adjusted the internal weight to eliminate it. Introducing the SK-POP Grande Hiramura Custom, which is capable of confronting big bass while inheriting the conventional horizontal floating and heavy bass POP sound.
