Ive fished a pink worm behind a diver with good results. Fish it just like you would bait.
Ive also fished them under a float and have hooked a few fish. One thing about a worm, It draws violent strikes.
I caught a few silvers on a trip this year fishing pink worms in an unconventional method. I will need to try it on more fish to see if it wasnt just a fluke thing.... I will report back on this one I get some more time in using the worms like that again.
