A great set of jigs for most any jigging application is the Bass Pro Shops Walleye Angler XPS Jigs. They come in sizes from 1/16 to 1/2 ounce. For dragging techniques I’d use 1/16 and 1/8 ounce. The head is a “semi-stand-up” so when it hits bottom it will keep the hook up just off bottom resulting in fewer snags. If you are vertical jigging – move up to a 1/4 or 3/8 ounce. The Bass Pro Walleye Angler XPS Jigheads are holographic, so you not only get multiple colors, but also flash. The hooks are Mustad Ultra Point so you will find that they stay sharper than other hooks – even when banged around on rocks and wood.
Good Luck Walleye Fishing
