Using the example has a problem at times, the top jig will wrap it self around the line. I usea different way to do this. I take about 5 ft of seagar fluro, and half way down tie a perfection loop, with a very big loop. I then cut the loop very close to the leader, and thats my top dropper, then using a cabelas rubber core sinker of any weight you want below the dropper and above the bottom bait.The leader is attached to my main line using a small snap and swivel. I tie several of these with different size jigs and tubes, and its easy to change rigs.
