I met the Gman at a BPS and he gave a great short seminar on drop-shotting. He added a little twist to his rig which is worth mentioning.
Imagine if you will, the very bottom of his rig was a split ring, above that was a tungsten bead and he used a tungsten bullet weight above that. About 18 inches above that was his hook to complete the rig. What you end up with, is a rig that with every little shake or hop makes noise.
