I do mine a little different. I use 6-8# fluoro. Swivel at the top, 18" or so to a snap swivel tied on dropshot style (palomar with the tag end going back down through the eye) and then another 18" to another snap swivel. Also use the Lindy rigger to keep several rigs ready. I use the snap swivels so I can swap jigs quicker and use just a hook and minnow if I need to.
If I need it to run deeper, I add a splitshot to the main line above the swivel or use a heavier jighead on the bottom snap swivel.
