To catch walleyes or magnum perch, start with a 2-foot length of 6-pound fluorocarbon or monofilament. At its end, tie a No. 10 treble hook, and above it slide on a neoprene bobber stop until it's anywhere from 6 to 10 inches above the treble. Add six 4mm chartreuse or orange plastic beads and a clevis with a No. 2 silver spinner blade. Tie the end of the leader to a swivel. Tip the treble with a 2- to 4-inch shiner.
