The dynamic vibration and the rolling action with the live aspect brought by VIOS Spindle Worm have a spectacular impact such as making the monsters you can not catch at the normal finesse game bite intrepidly. The spindle worm was developed seeking completely after the appropriate vibration and movement to pull lunkers far from the point of landing of lure or the retrieve range. The modeling of shape was done for the fishes bunched together in Zoning Institute. And the original shape adjusted for various & VIOS material develop the soft bait game of new level. The spindle worm is not only active as a normal swimming worm with no-sinker or jig-head rig but also displays the outstanding ability of reaction bite at the falling game of cover put into the tetra, the gap of big rocks, the weeds, and the bushes with Texas rig or Split shot rig. This is the multi-purpose worm you can use under various conditions in lots of ways. Spindle Worm/Heavy made the outstanding long casting with no- sinker possible because of “Heavy metal core” in the body, and made the small landing sound true. The swimming reaction is so attractive like the hard bait brought by appropriate balancing of the waited core with high specific gravity. The feeling is outclassing on swimming with no-sinker, falling, and deep-throw rolling with split shot rig. Thus, the stable swimming or the deep bottom contact will be made true with light Texas.
