By ribs dug in shallow, the pin tail worm produces the ultrafine wave full of  vitality. A variety of rig for light salt worm are produced, buy what the most  frequently used is a jig head rig. In this fishing is carried out with this  lightweight rig, ease of throwing is a very important element. If the weight of  the head simply become heavier, easy to make a distance, but cause of the  increasing of the weight, the range and the retrieve speed are restricted, then  the width to aim is narrowed. In the "Staple Fly", in order to earn a distance  with the lightweight jig head, the basic shape of the body has been  reconsidered. The peak of the body volume was extended to the rear body, and  further by the cross section makes angulated not circular, the volume of the  body itself increased. The weight of the worm body is increased while  suppressing the sense of volume of the body silhouette, and that also increase  the long-casting property. It seems also just a slight difference, but when you  actually use, the difference is large and the more it is a lightweight rig, the  more you can feel the difference. In the original size using a jig head of 0.8  g, as compared to the worm of the same sense of volume, about 22% distance  increasing (in this company's comparison). In the fishing of the light rig can  search narrow range this difference is big, the difference of the distance  appears inevitably as the difference of the catch. In addition, it is equipped  the support hole at the head part and the straight line at the back in order to  set the hook of the worm easily and accurately. in order to match the condition  of the field more, in addition to the original 2 inches, the 2.4 inches long  model that effective to the season when fishes eating small sardines and  whitebaits, and the 1.4 inches short model that is the breakthrough for the time  when fishes eat only opossum shrimps were added.  By selectively using the size, the corresponding power against seasonal pattern  has increased.
