Coyote,
Bill described it perfectly. Go to any local tackle store and ask them to show you their shakey heads, they all should have them. I prefer a 3/16th ounce head personally and I fish mine on 8 pound test florocarbon line and spinning tackle. Any finesse worm will work but like anything else you will find a certain bait and color you start to prefer. I really like the 5 inch slim senko. Just take your bait and twist it on the bait holder, rig it weedless and start fishing with any of the methods Bill mentioned above. It does take some getting used to but with time you will pick it up no problem.
