I always fish the worm with a float, run about a 3-5' leader from a barrel swivel attached to your mainline. I just use 3 or 4 splitshot on the leader under the swivel (water volume and current speed dictate the size). I use a regular bubble gum pink worm from culprit(the bass guys), non squiggly tail, about 5-6" length. I fish current seams where the faster current meets slow current, keeps your float from rippin down the river out of control. I'm no expert but I have caught a few fish in the last 2 years since starting to fish the worm. Good Luck!!!
