These jigs don't get hung up and cast well. Add a white pork grind to a blue or green jig.
Jigging is similar to using a small worm. Jiggle is forward inc by inc, wait between motion.
I have a friend in the UP of Michigan who is excellent fishing worms--very patient, a lot of slack in the line. When we met on a pond in Texas, I was better with jigs; he was better with worms. We learned from each other--subtleties of technique.
