There are many items in the BYS series that have been released to date that can be used as trailer baits, but the major difference from those items is the "fall action". When used as a jig trailer, this vice double flap not only appeals by moving the water with a large claw from the time of fall to the time of landing, but also the side parts (legs) of the body receive the water flow and fall Even during the staying time from the inside to the bottom, it receives the water flow and makes a delicate and lifelike movement to appeal, so after setting it on the jig, trim the rubber so that the legs of the worm come out, and it will land from the fall. Also, if you make your own jig (manually wind the rubber), it is recommended to wind a little rubber in advance.
